The siege of Wexford took place in early May 1169 and was the first major clash of the Norman invasion of Ireland. The town was besieged by a combined force of Normans under Robert Fitz-Stephen and soldiers loyal to Diarmait mac Murchadha. After being ousted as King of Leinster, Diarmait had recruited the Normans to help him regain control of Leinster and the semi-independent Norse-Gaelic seaport of Wexford. Although the attackers did not breach the town's walls, Wexford surrendered after almost two days and came under Norman control.
