On 23 March 1921 the IRA in Co Roscommon ambushed a convoy of British military and members of the RIC as they travelled from Strokestown towards Longford. The ambush took place in a rural area called Scramogue. This is the story of that engagement along with detailed background of events in the county leading up to the ambush and its aftermath. The story is recounted here by Roscommon historian Henry Owens.
