Peter Daly (27 September 1903 – 5 September 1937) was an Irish Socialist and Republican who fought in the Irish War of Independence as well as serving as a volunteer in the Spanish Civil War, where he died serving with the International Brigades. Following the civil war, Daly departed to England where after a stint of working odd jobs, he eventually joined the British army in 1926. Daly served for 4 years and reached the rank of Sergeant before being dishonourably discharged (in his absence) after it became apparent that he was smuggling small arms back to Ireland.
