Daly found his forces under increased pressure from pro treaty forces. Facing overwhelming opposition Daly and the O/C the IRAs 1st Northern Division, Sean Lehane split their forces into smaller columns. In a letter dated 17 September 1922, Daly expressed his forces desperate situation: "Here we are with one small column trying to hold our own against desperate odds. A month ago I never expected that one of us would be left by now." Arrest, execution and legacy On 2 November 1922, Charlie Daly was captured and imprisoned at Drumboe Castle in Donegal, where he was held until 16 January 1923, when he was court-martialled and sentenced to death. On 14 March 1923, Commandant General Daly (aged 26), Lt. Daniel Enright (aged 23), Brigadier Commandant Sean Larkin (aged 26), and Lt. Timothy O'Sullivan (aged 23) were given an opportunity to prevent their execution if they each signed the following "Declaration": "I promise that I will not use arms against the Parliament elected by the Irish people, or the Government for the time being responsible to that Parliament, and that I will not support in any way such action. Nor will I interfere with the property or person of others." All four men refused to sign and faced a firing squad shortly thereafter. Like Daly, Enright and O'Sullivan were also from Kerry.

Joseph Sweeney (Irish politician) was the Commander of the Provisional Government forces in Donegal and knew Daly from earlier years.

His sister May Daly was a significant figure in Sinn Féin in Kerry up to the 1970s; she stood in the 1957 general election in Kerry North, polling 3,171 votes.
