A monument entitled Memorial to the Confederate Dead was placed in Jefferson Barracks on May 1, 1988 It is located in section 66 of the cemetery. Not to be confused with the removed Memorial to the Confederate Dead (St. Louis).

It was placed by the Jefferson Barracks Civil War Historical Association, Sons of Confederate Veterans, and the Missouri Society Military Order of the Stars and Bars. The front of the monument features three Confederate flags: the first national flag (seven-star variant of the "Stars and Bars"), the Confederate Battle Flag, and the last national flag ("Blood-Stained Banner").

Under the flags is a quote by Berry Benson:

To the Confederate Dead 1861–1865 Who knows but it may be given to us, after this life, to meet again in the old quarters, to play chess and draughts, to get up soon to answer the morning roll call, to fall in at the tap of the drum for drill and dress parade and again to hastily don out war gear while the monotonous patter of the long roll summons to battle? Who knows but again the old flags, ragged and torn, snapping in the wind, may face each other and flutter, pursuing and pursued, while the cries of victory fill a summer day? And after the battle, then the slain and wounded will arise, and all will meet together under the two flags, all sound and well, and there will be talking and laughter and cheers, and all will say: Did it not seem real? Was it not as in the old days?”
