Two irregulars - Nicholas Corcoran and Thomas Gill - were captured by the National Army in March 1923 in Massbrook, near Crossmolina. Corcoran was discovered with a revolver, ammunition, and explosives. A few days later, Jack Leonard was arrested in his home in Crossmolina. Leonard was the photographer who took one of the most iconic images of the War of Independence - "the Men of the West". It is the photo of the West Mayo IRA Flying Column, taken at Derrymartin on the slopes of Nephin mountain, in June 1921. It is widely regarded as the best contemporary photograph of an IRA Active Service Unit ever taken.
