The city surrendered on 13 August. The regiment suffered twelve deaths, with one officer and 23 men wounded, during the campaign. The 56th remained as part of the Havana garrison for the following year, until Cuba was returned to Spain by the Treaty of Paris, when it was transported to Ireland, arriving in Limerick in October 1763. The regiment moved to Dublin in May 1765, and in June 1765 the colonelcy was assigned to Lieutenant-General James Durand. He died in 1766, and was succeeded by Colonel Hunt Walsh.
