Schematic plan · World War II (Italy 1943-1944)

Battle of Amphitheater

9 September 1943
Italy
Victory for Great Britain

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.

Great Britain (Br 56th Inf Div, 12,917 men under Mg Graham) attacked Germany (Ger 16th Pz Div (Elms), 4,250 men under Mg Sikenius) in Italy. The CAA Database of Battles records 48 hours of fighting on a front of 13 km, a frontal attack against hasty defense and prepared defense, and that Great Britain won. Losses: Great Britain 1,154 (9%), Germany 100 (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.
