The 18th Infantry Division was an infantry division of the British Army which fought briefly in the Malayan Campaign of the Second World War. In March 1939, after the re-emergence of Germany as a European power and its occupation of Czechoslovakia, the British Army increased the number of divisions in the Territorial Army (TA) by duplicating existing units. The 18th Infantry Division was formed in September 1939 as a second-line duplicate of the 54th (East Anglian) Infantry Division, with men from Essex and the East Anglian counties of Norfolk, Suffolk and Cambridgeshire.

The division was based in Britain from 1939 to 1941, undergoing training and being moved around the country. This included an anti-invasion role in East Anglia, training in Scotland, and redeployment to the North West where the division also helped unload merchant ships during the Liverpool Blitz. Towards the end of 1941, the British government sought to reinforce the British Army in North Africa to demonstrate to the Dominions that the United Kingdom was doing its fair share of fighting in the Middle East and to prepare for Operation Crusader. The division left Britain during October bound for Egypt.

By December, the convoy had reached South Africa and was preparing for the final stretch of its journey when news of the Japanese entry into the war was received. This resulted in most of the 18th Infantry Division being diverted to India to reinforce British forces facing the Japanese. The 53rd Brigade was sent to Singapore, from where it was deployed north to Johore and became embroiled in the Battle of Muar. After several short engagements with Japanese forces, the brigade was withdrawn to Singapore Island. Between 29 January and 5 February, the rest of the division arrived in Singapore having sailed from India. Shortly afterwards, the entire division participated in the Battle of Singapore.

Initially deployed to northeastern Singapore Island, the division remained largely inactive while the Japanese attacked the north-west sector. Following the establishment of a Japanese beachhead, the division was broken up and deployed piecemeal in the battle. One battalion was assigned to a different formation and several units formed two battlegroups. After the initial engagements, the division was regrouped for a final stand in the city of Singapore and repulsed several Japanese attacks. The division, with the rest of the garrison, surrendered to the Japanese on 15 February 1942. It was not reconstituted. Over one-third of the division's personnel died in captivity, including divisional commander Major-General Merton Beckwith-Smith.

During the 1930s, tensions increased between Germany and the United Kingdom and its allies. In late 1937 and throughout 1938, German demands for the annexation of Sudetenland in Czechoslovakia led to an international crisis. To avoid war, the British Prime Minister Neville Chamberlain met with German Chancellor Adolf Hitler in September and brokered the Munich Agreement. The agreement averted a war and allowed Germany to annexe the Sudetenland. Although Chamberlain had intended the agreement to lead to further peaceful resolution of issues, relations between both countries soon deteriorated. On 15 March 1939, Germany breached the terms of the agreement by invading and occupying the remaining Czech provinces of Bohemia and Moravia.

On 29 March, British Secretary of State for War Leslie Hore-Belisha announced plans to increase the Territorial Army (TA), a reserve of the regular army made up of part-time volunteers, from 130,000 to 340,000 men and double the number of TA divisions. The plan was for existing units to recruit over their establishments, aided by an increase in pay for Territorials, the removal of restrictions on promotion which had hindered recruiting, the construction of better-quality barracks, and an increase in supper rations. The units would then form second-line divisions from cadres which could be increased. The 18th Infantry Division was a second-line unit, a duplicate of the first-line 54th (East Anglian) Infantry Division. In April, limited conscription was introduced. This resulted in 34,500 twenty-year-old militiamen being conscripted into the regular army, initially to be trained for six months before deployment to the forming second-line units. Despite the intention for the army to grow, the programme was complicated by a lack of central guidance on the expansion and duplication processes and a lack of facilities, equipment and instructors.

It was envisioned that the duplicating and recruiting processes would take no more than six months. Although some TA divisions had made little progress by the time the Second World War began, others completed this work within weeks. The 18th Infantry Division became active on 30 September 1939; prior to this its units had formed, and were administered by the parent 54th (East Anglian) Infantry Division. The 18th Division was composed of the 53rd, 54th and 55th Infantry Brigades, and divisional support troops. The division was formed with men from the county of Essex and the East Anglian counties of Norfolk, Suffolk and Cambridgeshire. According to the Imperial War Museums, its insignia (windmill sails) denotes "the association of the Division with East Anglia". The 53rd Brigade consisted of the 5th Battalion, Royal Norfolk Regiment (5RNR), 6th Battalion, Royal Norfolk Regiment (6RNR), and the 2nd Battalion, Cambridgeshire Regiment (2CR). The 54th Brigade controlled the 4th Battalion, Royal Norfolk Regiment (4RNR), 4th Battalion, Suffolk Regiment (4SR), and the 5th Battalion, Suffolk Regiment (5SR). The 55th Brigade was made up of the 5th Battalion, Bedfordshire and Hertfordshire Regiment (5BHR), 1st Battalion, Cambridgeshire Regiment (1CR), and the 1/5th Battalion, Sherwood Foresters (1/5SF). The division's first general officer commanding (GOC) was Major-General Thomas Dalby, who had been brought out of retirement.

Major-General Bernard Paget assumed command on 30 November 1939, replacing the again-retiring Dalby. The division was initially assigned to Eastern Command, and was based in Norfolk by early 1940. The opening months of the war allowed little time to train, and the division guarded airfields and other key points. By summer, it was under the command of II Corps and was spread throughout Cambridgeshire, Norfolk and Suffolk. On 20 April, Paget left the division temporarily and was replaced by Brigadier Edward Backhouse (commander of 54th Brigade). Paget was deployed to Norway, where he commanded Sickleforce (the 15th and 148th Infantry Brigades) after their landing at Åndalsnes during the Norwegian Campaign. When the campaign failed, Paget returned briefly to the division on 14 May 1940; thirteen days later, he became Chief of Staff, Home Forces and was temporarily replaced by Brigadier Geoffrey Franklyn.

The TA's war deployment envisioned its piecemeal use, as equipment became available, to reinforce the British Expeditionary Force (BEF) already dispatched to Europe. The TA divisions would the join regular army divisions as the divisions completed their training and received their equipment, with the final divisions deployed a year after the war began. The division did not leave Britain at that time, since the BEF was withdrawn from France during the May–June 1940 Dunkirk evacuation. The evacuation had resulted in the abandonment of much of the BEF's equipment, leaving troops in Britain sparsely equipped. Priority for new equipment was given to a handful of formations that would respond to any German landings, leaving the 18th Division with little of what was required. An infantry division should have been equipped with seventy-two 25-pounder field guns; on 31 May 1940, the 18th Division was equipped with four First World War-vintage 18-pounder field guns and eight 4.5-inch howitzers of similar age. The division had no anti-tank guns (compared with the usual 48), and only 47 of the required 307 Boys anti-tank rifles.

During the summer of 1940, the 18th Infantry Division had several changes of command. Major-General Thomas Eastwood took command on 1 June before leaving to become chief of staff of the Second BEF under the command of Lieutenant-General Alan Brooke. Major-General Lionel Finch, previously Director of Recruiting and Organization and Deputy Adjutant-General to the Forces, took command on 9 June before his replacement by Major-General Merton Beckwith-Smith (who had commanded the 1st Guards Brigade during the Battle of France) on 14 July. He remained with the division for the remainder of its existence.

Although the division was then assigned to an anti-invasion role in East Anglia, a number of training exercises were held in other parts of England as well as in Scotland, and Wales. In the autumn of 1940, it moved permanently to Scotland. Divisional headquarters was established at Melrose, with the troops spread across the Scottish Borders from Dumfries to Duns. Further divisional exercises were conducted, facing contingents of exiled Belgians, Czechs, Norwegians, and Poles. Unfounded rumours began to circulate that the division would soon be deployed overseas.

It was assigned to Western Command and moved to North West England and the West Midlands in April 1941, replacing the 38th (Welsh) Infantry Division. The division was spread out between Liverpool, Manchester and Birmingham, with divisional headquarters at Ribbesford House near Bewdley. During the Liverpool Blitz, several hundred men were deployed to the city for several weeks to help unload cargo ships. This deployment saw the division's first casualties of the war, due to German bombing. On 18 July, Brooke (now Commander-in-Chief, Home Forces) inspected elements of the division which were based in Crewe.

Winston Churchill, who has succeeded Chamberlain on 10 May 1940, had grown concerned in 1940 about the expansion of British supply services in Egypt under Middle East Command compared to the number of fighting men, and pushed for the dispatch of additional fighting formations. This had been a source of friction with General Archibald Wavell and his replacement, General Claude Auchinleck, who wanted rear-area personnel and replacements for fighting formations rather than new divisions. Churchill was adamant that additional complete British fighting formations be dispatched, not replacements or logistical troops, "to give the Dominions no cause to feel that the bulk of the fighting was done by their troops". On 1 September 1941, Churchill contacted neutral U.S. President Franklin D. Roosevelt and requested shipping for two infantry divisions from Britain to the Middle East. Roosevelt responded that shipping could be provided for only one division, sailing from Halifax, Nova Scotia. The 18th Infantry Division left Liverpool aboard the heavily escorted convoy CT.5 on 28 October, bound for Nova Scotia. Three days later, an American-escorted convoy left Halifax with six cargo ships provided to the British as part of the Lend-Lease programme. The convoys met in mid-ocean on 2 November, and exchanged escort groups; the British ships and Lend-Lease cargo ships headed for the United Kingdom, and the (now American-escorted) convoy CT.5 continued to Nova Scotia. The division arrived in Halifax on 7 November, and transferred to the waiting American ships of convoy WS.12X over the next few days. The British ships returned home, and convoy WS.12X departed Halifax on 10 November for the Middle East.

During the night of 7/8 December 1941, one hour before its attack on Pearl Harbor, the Empire of Japan began the invasion of Malaya. Four hours after the attack on Pearl Harbor, the Battle of Hong Kong began. Although the immediate British response was to order a number of units to be diverted to the Far East, none based in the Middle East were withdrawn for the moment. Since the convoy containing the 18th Infantry Division had only reached the Cape of Good Hope when Japan entered the war, it was diverted to the Far East on 9 December. Instead of reinforcing Operation Crusader as planned, the division was sent to India. Lionel Wigmore, the Australian historian of the Malayan campaign, wrote that the diversion indicated that "... the security of Singapore and maintenance of Indian Ocean communications were second in importance only to the security of the United Kingdom ..."

Most of the division arrived in Bombay on 27 December. The 53rd Infantry Brigade stopped for a week at Mombasa, Kenya and was diverted on 23 December to Malaya. The brigade, travelling on the USS Mount Vernon with the 135th Field Regiment, Royal Artillery and the 287th Field Company, Royal Engineers, arrived at Singapore on 13 January 1942 without its artillery or transport. Although the rest of the division was under War Office control, the 53rd Brigade was temporarily detached and assigned to Malaya Command. Their equipment, scheduled to arrive on a later convoy, was made up from local sources. It was hoped that the brigade could be put into the line immediately (relieving the 22nd Australian Brigade) but its men were considered unfit for immediate action after eleven weeks at sea. By the time the brigade arrived, the Japanese had forced Allied forces to retreat south. On 11 January, Kuala Lumpur, the capital of British Malaya, fell; Japanese forces reached Johor, the southernmost state of Malaya, soon afterwards.

On 17 January, despite reservations about the state of the brigade's fitness, a brigade group based on the 53rd Brigade (under the command of Brigadier Cecil Duke) had arrived in the Ayer Hitam area of Johor and elements were attached to the 11th Indian Infantry Division in III Indian Corps to reinforce the defences from Batu Pahat to Yong Peng. 6RNR was deployed around 10 miles (16 km) to the west to defend a tactically important defile and causeway between Bukit Pelandok (south of the pass) and Bukit Belah (to the north). 2CR relieved the garrison at Batu Pahat, around 15 miles (24 km) southwest of Ayer Hitam. Both battalions were also assigned to patrolling the roads against Japanese infiltration. Japanese patrols were soon encountered by 2CR southwest of Batu Pahat, and 6RNR (near Bukit Pelandok) was attacked from the air. 5RNR was allocated to Westforce (an ad hoc multi-national force assembled under the command of Australian Major-General Gordon Bennett) to relieve the 2/19th Australian Battalion at Jemaluang. Several Australian officers were to remain behind and aid 5RNR in taking over their positions and one said:

They were a fine body of men but almost dazed by the position in which they found themselves. Their training had been for open warfare and not the very close warfare of the Malayan countryside. They demonstrated the unreality of their approach to the situation by lighting up all the buildings in the area, [and] stringing their transport along highly vulnerable and prominent crossroads....

— Unnamed Australian officer

The battalion had not completed its move, when on 19 January the troops were ordered to Ayer Hitam. The defile had become a crucial position in the British attempt to delay the Japanese advance and prevent them from cutting off the 45th Indian Infantry Brigade. 6RNR was to be reinforced by the depleted 3rd Battalion, 16th Punjab Regiment (3/16PR) and the untried 2nd Battalion, Loyal Regiment (North Lancashire) (2LR) from the 9th Indian Division as the 45th Indian Infantry Brigade retired through the 53rd Infantry Brigade positions to an area west of Yong Peng and Westforce withdrew to Labis. At 13:30 on 19 January, elements of the Japanese I Battalion, 5th Guards Infantry Regiment, Imperial Guards Division surprised a 6RNR company in Bukit Pelandok and occupied the lower slopes of Bukit Belah, commanding the Bakri road. Another 6RNR company managed to hold on at the northern slope of Bukit Belah and later took over the peak, unknown to battalion headquarters. At 05:00 on 20 January, 3/16PR was to counter-attack and recapture Bukit Belah and the northern ridge by dawn on 20 January and then 6RNR was to attack the Japanese in Bukit Pelandok covered by fire from Bukit Belah. The Punjabi attack began at 04:00, but they were mistaken for a Japanese unit by 6RNR company on the summit of Bukit Belah, who opened fire. The Indians managed to reach the peak, but before it could be consolidated, a Japanese attack forced the British and Indian troops off the ridge with many losses, including the Punjabis' commander. The attack on Bukit Pelandok was repulsed and the British and Indian troops were moved to between the defile and causeway with the left flank covered by 2LR.

The delayed brigade counter-attack was ordered for dawn on 21 January, spearheaded by 2LR, but 6RNR and 3/16PR were incapable of attacking so soon and 2LR had only just arrived; the attack was postponed again, but with orders to begin as soon as possible. At 20:00, Lieutenant-General Arthur Percival, GOC Malaya Command, decided that the Japanese capture of the Pelandok defile seriously endangered Westforce's line of communications. He ordered Bennett to continue to withdraw south of Labis to a line from Paloh to the Sungei Gerchang bridge on the road to Labis, and to detach a brigade as soon as possible to dig in at the Yong Peng road junction. As the 27th Australian Brigade covered Yong Peng, Percival put all troops on the Muar–Yong Peng road back under the command of Westforce at 12:30. The counter-attack by the 53rd Brigade never occurred; at 10:30 on 21 January, Major-General Billy Key (GOC 11th Indian Division) visited the brigade and learned that half his orders had not been transmitted, that the brigade had not planned an attack, and that 2LR had been sent to dig in at the east end of the causeway. An attack could be arranged for 14:00, but more confusion occurred, and the start time was moved to 15:30. The Japanese positions gave a view of the ground east of the ridge, making surprise impossible to achieve, and more time was needed to arrange artillery support and concentrate 2LR. The attack was postponed again to 18:00 and then to the morning of 22 January. The artillery took so long to register that there was another postponement to 09:00, but 2LR, who had assembled under cover of night, were spotted by Japanese reconnaissance aircraft and bombed and strafed. With no prospect of surprise, and doubtful that the attack could succeed, Duke cancelled the operation and redeployed the three battalions to guard the causeway and the ground from there to the defile.

At 06:30 on 22 January, 5RNR and a battalion from Batu Pahat reopened the Batu Pahat–Ayer Hitam road at Milestone 72 and a supply convoy got through to the brigade. Later, the Japanese again blocked the road. Key ordered 5RNR to reopen the road along with an attack by the 15th Indian Infantry Brigade on 23 January, but this attack failed and 5RNR was recalled. At a conference at Yong Peng, also on 23 January, Percival announced a new plan to defend a line from Jemalaung Kluang to Ayer Hitam and Batu Pahat, the 53rd Brigade reverting to the command of the 11th Division. The brigade was to retire on 23 January through the positions of the 27th Australian Brigade at Yong Peng to Ayer Hitam, when the transfer of command would occur. 5RNR was driven by bus to Pontian Kechil, ready to travel with an ammunition convoy to Batu Pahat, next morning. The brigade began to retire from Bukit Pelandok at noon, but the Japanese attacked with tank support and the causeway bridges were blown too soon for all the British to cross. In the chaos the brigade managed to disengage, but with many casualties. With the other battalions assigned to specific duties, the 53rd Brigade was reduced to the 6RNR and 3/16PR and moved south to Benut via Skudai. The brigade was engaged in a series of isolated fights with the Japanese along the road from Benut to Senggarang as they tried to move north to reinforce Batu Pahat. Only isolated elements were able to reach Senggarang, to which the 15th Indian Infantry Brigade, including 2CR and 5RNR, had retired. During the evening, the 15th Indian Brigade was ordered to break out, across country as the roads had been blocked by strong Japanese positions, and retreat south. During the night of 29/30 January, the 53rd Brigade was ordered to withdraw to Singapore Island; the brigade had suffered about 500 casualties.

On 20 January, Wavell visited Singapore to discuss the defence of the island with Percival. During this conference, it was decided that once the 18th Infantry Division had arrived in full force, it would be allocated to the sector on the island believed to be where the Japanese would land, as it would be the strongest formation available with fresh troops. Percival believed that this would be the northeast part of the island; Wavell disagreed stating it would be the northwest section of the island (where the Australians were to be deployed). However, he did not force the issue and allowed Percival to deploy his forces as he wished. Wigmore commented that Wavell conceded the point "on the ground that [Percival] was the commander responsible for results and had long studied the problem."

The majority of the 18th Infantry Division arrived in Singapore on 29 January, followed by the final elements (the machine-gun and reconnaissance battalions) on 5 February. Once the main body had landed, the 53rd Brigade returned to the division. The 18th was assigned to III Indian Corps and deployed in strength along the northeast section of the coastline. Their objective, as with all other frontline forces, was to prevent the Japanese from landing or if a landing did occur, to stop the Japanese on the beaches and launch counter-attacks to destroy their beachheads.

On 5 February, Japanese forces made obvious movements on the mainland opposite the 18th Division and bombarded the 18th Division positions for several days. The same day, aircraft bombed the Empress of Asia; one of the four vessels that was bringing the remainder of the division to Singapore. Following the attack, Percival and Bennett reviewed Allied dispositions and expressed concern that they would not be able to defend the island without reinforcements.

Three days later, at 22:30 on 8 February, the Japanese began their assault on Singapore Island, landing on the northwest coast against Australian opposition. The 18th Division was ordered to remain where it had been posted in case of a second landing, and took no part in the initial fighting. After two days of fighting, Churchill cabled Wavell, "The 18th Division has a chance to make its name in history. Commanders and senior officers should die with their troops. The honour of the British Empire and of the British Army is at stake. I rely on you to show no mercy to weakness in any form." The character of Churchill's message was then relayed via Wavell to the troops. During the day, by which time Percival had drawn up a provisional plan to withdraw to a smaller perimeter around the city of Singapore, the division was committed piecemeal in the effort to stem the Japanese advance. The 5BHR was taken from the division and assigned to the 1st Malaya Infantry Brigade. Two ad hoc formations: Tomforce, from the divisional reconnaissance battalion, 4RNR, 1/5SF and a battery of the 85th Anti-Tank Regiment, under the command of Lieutenant-Colonel Lechmere Thomas; and Massy Force from 1CR, 4SR, the Indian 5th Battalion, 11th Sikh Regiment (5/11SR), and various other units including artillery and 18 light tanks, under the command of Brigadier Tim Massy-Beresford (commander of the 55th Brigade). The rest of the division remained in its sector.

On 11 February, Tomforce, having moved to reinforce the Australians, launched a counter-attack on the captured village of Bukit Timah. The reconnaissance battalion was ordered to advance up the main road to the village, with 4RNR to their right and the 1/5SF (reinforced with elements of the 2/29th Australian Battalion, who had been temporarily attached to Tomforce) to their left. The reconnaissance battalion encountered strong Japanese resistance as they tried to enter the village near the railway station and could proceed no further. On their flank, the 1/5SF and the Australians advanced to within 400 yards (370 m) of the village, before being forced back. 4RNR took control of an area of high ground overlooking the village, but could advance no further due to a strong Japanese presence in the area. Meanwhile, Massy Force had assembled on the eastern side of MacRitchie Reservoir and was ordered to defend Bukit Tinggi, west of the reservoir, but Japanese forces arrived first. During the afternoon, Massy Force moved to the northern end of Bukit Timah Race Course and linked up with Tomforce who had pulled back following their failed attack on Bukit Timah. Late in the day, Massy Force absorbed Tomforce and the latter ceased to exist. It was later established that the Japanese 5th and 18th Divisions had occupied the area.

The following day, with half the island under Japanese control, fighting intensified. The Japanese 5th Infantry Division, supported by tanks, attacked along the entire front, including the position held by Massy Force. Elements of Massy Force were pushed back and a Japanese tank attack penetrated deep into the British positions, before they were repulsed. Following the attack, Massy Force was withdrawn 3,000 yards (1.7 mi; 2.7 km) to a position along the Adam and Farrer roads. During the day, the rest of the 18th Infantry Division was ordered to move from their coastal positions. The 53rd Brigade and the 2/30th Australian Battalion covered the withdrawal of the 8th and 28th Indian Infantry Brigades, while the remnants of the division (along with the 11th Indian Division) were ordered to take up positions covering the Peirce and MacRitchie reservoirs.

On 13 February, the division had moved into the final defensive perimeter established around Singapore. This position lacked any fortifications and it was clear all hope of victory had gone. The division was deployed with Brigadier Backhouse's 54th Brigade on the left astride the road to Bukit Timah (north-west of the city), to their right was the 53rd Brigade positioned north of the Chinese cemetery and Massy-Beresford's 55th Brigade (on the right flank) was north of the city from Thomson Road to the Adam Park Estate. The Japanese attacked at numerous points along the final defensive perimeter, including several assaults on the Adam Park Estate. The 1CR fought off several attacks, including bayonet charges, inflicting over 600 casualties for the loss of 165 men. On 14 February, further attacks penetrated between the 53rd and 55th Brigades. Reinforcements from the 11th Indian Division were dispatched, repelled the Japanese attack and sealed the gap.

Despite the Japanese attacks, the defensive line held; with food, water and ammunition running out, Percival decided on 15 February that counter-attacks would be fruitless. To spare the civilian population of the city further hardship, the decision was made to surrender the Allied garrison. The order to surrender surprised the men; some fled, fearing that the Japanese would not take prisoners and others had to be pressured into laying down their arms. Some, such as Harold Atcherley (an intelligence officer with the division) were ordered off the island, but Atcherley failed to escape. On 15 February, the division ceased to exist and its men entered Japanese captivity. The division was never reconstituted in the United Kingdom. During the next three years, over one-third of the men died in Japanese captivity; Beckwith-Smith succumbed to diphtheria on 11 November 1942.

In the aftermath, the division was a political bargaining chip in a series of telegrams between Churchill and Prime Minister of Australia John Curtin which discussed the possibility of diverting Australian troops to Burma rather than returning home. On 20 February, Churchill sent a telegram,

... your message of January 23, in which you said that the evacuation of Singapore would be "an inexcusable betrayal". Agreeably with your point of view, we therefore put the 18th Division ... into Singapore instead of diverting them to Burma, and ordered them to fight it out to the end. They were lost at Singapore and did not save it, whereas they could almost certainly have saved Rangoon. I take full responsibility with my colleagues on the Defence Committee for this decision; but you also bear a heavy share on account of your telegram.

— Churchill

Two days later, Curtin retorted: "In regard to your statement that the 18th Division was diverted from Burma to Singapore because of our message, it is pointed out that the date of the latter was January 23, whereas in your telegram of January 14 you informed me that one brigade of this division was due on January 13 and the remainder on January 27".

According to historian Brian Padair Farrell, Wavell's decision to allow the 18th Infantry Division to be deployed to Singapore was "the least blameworthy of the decisions that he made which had negative consequences—especially for the men of the 18th Division who suffered the terrible years of captivity under barbaric Japanese control". Farrell noted that "Wavell's job was to hold Singapore" and "no other commander in his place would have chosen differently". Gerhard Weinberg wrote that "the constant splitting of divisions ... and the piecemeal tossing of reinforcements into battle all contributed to defeat". This was echoed by Captain Henry Phillips, a former member of the division, who wrote that the division "had been prodigally thrown to the winds", was ill-trained for the situation, and received no intelligence about how the Japanese were armed, dressed, or equipped;

... [T]he division was not permitted to fight as a division ... battalions were divorced from brigades and companies from battalions. Unnecessary difficulties of administration were created and the chain of command disrupted." Phillips called the battle an "unredeemed disaster", and asked for the "misapplication of the 18th Division" to be scrutinised by a public inquiry "to throw more light on the current of events contingent upon so important and so tragic an event in our military history.
