England (Eng Army, 18,000 men under Ginckel) attacked Jacobites (Eng & Irish Reb Army, 25,000 men under St. Ruth) in Ireland. The CAA Database of Battles records 6 hours of fighting on a front of 6.4 km, a frontal attack against hasty defense and prepared defense, and that England won. Losses: England 2,700 (15%), Jacobites 4,400 (18%).

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.
