Germany (Ger 11th Army, Aus 3rd(-) & 4th Armies, 216,000 men under Gen Mackensen) attacked Russia (Rus 3rd Army, 219,000 men under Gen Dimitriev) in Austrian Galicia. The CAA Database of Battles records 48 hours of fighting on a front of 121 km, a frontal attack against prepared defense, and that Germany won. Losses: Germany 36,000 (17%), Russia 153,654 (70%).

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.
