Cause

Enniskillen Castle had been under siege by Irish forces under Hugh Maguire since May 1594. The English dispatched a column of nearly 650 soldiers led by Sir Henry Duke to relieve and resupply the garrison, marching through the difficult boggy and wooded terrain of Ulster.

Event

On 7 August 1594, the English relief column was ambushed at the Arney River by a Gaelic Irish force commanded by Hugh Maguire and Cormac MacBaron O'Neill. The attackers exploited the terrain to devastating effect, defeating the column and scattering its supplies, including hard biscuits, into the river — giving the battle its distinctive name.

Consequence

The English suffered at least 56 killed and 69 wounded, and were forced into a hasty retreat. The defeat exposed how vulnerable English columns were to ambush tactics in Ulster's forests and bogs, providing an early indicator of the strategic challenges England would face throughout the Nine Years' War.
