Schematic plan · World War II (Italy 1944)

Battle of San Martino

1800
Italy
Victory for USA

A schematic plan, generated from the statistics of the CAA Database of Battles: the armies' size and width, the hours of fighting, the plan of attack and the outcome are as recorded; the ground and the positions are not.

USA (US 85th Inf Div(+), 17,970 men under Mg Coulter) attacked Germany (Ger 94th Inf Div(-), 8,141 men under Mg Steinmetz) in Italy. The CAA Database of Battles records 3.5 hours of fighting on a front of 5.5 km, a frontal attack against fortified defense, and that USA won. Losses: USA 1,974 (11%), Germany 720 (9%).

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.
