One of the 13 engagements of the Battle of Belleau Wood recorded in the CAA Database of Battles (number 5 in date order). USA (US 23rd Inf Rgt, 3,608 men under Col Malone) attacked Germany (Ger 1/47th Inf Rgt(+), 3,955 men under Lcol Rotenbucher) in France. The CAA Database of Battles records 10 hours of fighting on a front of 1.6 km, a frontal attack, single envelopment, right flank against prepared defense, and that Germany held. Losses: USA 340 (9%), Germany 87 (2%).

This plan is generated from those figures. It shows the shape of the battle the database describes: the size and width of the armies, the plan of attack and the outcome. It does not show where the units actually stood.

Notes

On this reconstruction

Generated automatically from the statistics in CDB90. Frontages, depths, distances, the order of events and the terrain are schematic: they follow the recorded strengths, front widths, hours of fighting, tactical plan and outcome, not maps or accounts of the battle. The sources give no hours; the timing is conjectural.
