8 September 1798: The Battle of Ballinamuck/ Cath Bhéal Átha na Muc  was fought on this day. It was the last battle on Irish soil of the 1798 Rising. A vastly superior British force under General Lake cornered a small Franco-Irish Army under the command of General Humbert. After a desultory exchange of fire the French accepted terms and laid down their weapons. No such considerations were offered to the Irishmen who accompanied him on his march on Dublin. Armed for the most part with pikes and agricultural instruments they were shot and cut down in their hundreds as a general massacre began.

As the Irish stood defenceless on Shanmullagh Hill overlooking the village, volleys of musket shot was poured into them, followed by a cavalry charge, and an estimated five hundred souls perished in the carnage. After it was all over their bodies were gathered together and unceremoniously buried in a mass-grave, known ever since as the ‘Croppies grave.’ Their final resting place is marked by a modest cross, erected by the local people who care for the site on a voluntary basis. A memorial stone marks the spot.

96 French officers and 748 men were taken prisoner. British losses were initially reported as 3 killed and 16 wounded or missing, but the number of killed alone was later reported as 12. Approximately 500 Irish lay dead on the field, 200 prisoners were taken in the mopping up operations, almost all of whom were later hanged, including Matthew Tone, brother of Wolfe Tone. The prisoners were moved to Carrick-on-Shannon, St Johnstown, today's Ballinalee, where most were executed in what is known locally as Bully's Acre.

Humbert and his men were taken by canal to Dublin and repatriated. The British army then slowly spread out into the rebel held "Republic of Connaught" in a brutal campaign of killing and house burning which reached its climax on 23 September when Killala was stormed and retaken with much slaughter.
