Siege of Limerick (1642)
The city of Limerick was besieged a total of five times in the 17th century. Two of these sieges took place during the Eleven years war (1641-1653). The first of these happened in 1642, when Irish Catholic Confederate troops besieged and took the citadel of King John's Castle from an English Protestant garrison.
The 1641 rebellion in Limerick
The Irish Confederacy’s taking of Limerick was made far easier than subsequent attempts by the fact that they had the support of most of the city’s population. About 600 English Protestant settlers had fled to the city to escape the Irish Rebellion of 1641 and had fortified themselves in King John's Castle in the centre of Limerick. The city was predominantly Catholic and appealed to the new Confederate Catholic government at Kilkenny to capture this Protestant citadel.
Confederate troops arrive
As a result, Garret Barry, a Confederate general marched to Limerick with 1,500 men to secure it. Since he had no siege artillery, Barry put his men to work digging mines under the walls of the castle, which he intended to collapse by burning their supports. He also positioned snipers in the houses surrounding the castle to harass the defenders, particularly in St. Mary's Cathedral, which overlooked King John’s Castle. Finally, he cut off the defenders' food and water supply.
The castle surrenders
After four weeks, when the English Protestants were ravaged by disease, and many were wounded, they surrendered on terms, before Barry had to collapse his mines and assault the castle. The 400 surviving Protestants were evacuated to Dublin.
