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.

Italy (It 2nd & 3rd Armies, 200,000 men under Gen Cadorna) attacked Austria (Aus 5th Army, 100,000 men under Gen Borojevic) in Austria. The CAA Database of Battles records 336 hours of fighting on a front of 16 km, a frontal attack, river crossing against fortified defense, and that Austria held. Losses: Italy 14,947 (7%), Austria 9,958 (10%).

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.
