One of the 7 engagements of the First Battle of the Marne recorded in the CAA Database of Battles (number 7 in date order). Germany (Ger 5th Army, 142,000 men under Cr Pr Wilhelm) attacked France (Fr 3rd Army, 180,000 men under Gen Sarrail) in France. The CAA Database of Battles records 72 hours of fighting on a front of 64 km, a frontal attack, single envelopment, left flank against hasty defense, and that France held. Losses: Germany 29,000 (20%), France 29,000 (16%).

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.
