The town of Ballyneety unexpectedly saw action relating to The Siege of Limerick. On 10th August 1691, a Williamite siege train on its way from Dublin to Limerick camped at the town.

Patrick Sarsfield hearing the train was on its way requisitioned a force of 500 cavalry, and with a local man named Hogan as guide, left Limerick City they made their way up the Clare side of the Shannon, crossing the river under cover of darkness above Killaloe. They camped near Keepers Hill, setting out early in the morning of the 11th they intercepted the train at Ballyneety, taking the Williamite's completely by surprise and overwhelming them, unfortunately there were some civilian casualties, including women and children.

Of the eight guns the siege train was carrying two were completely destroyed, the other six had their carriages wrecked. Sarsfield's men gathered the powder and ammunition together in a pile and laying a gunpowder trail blew it up, it is said the the resulting explosion was the loudest noise ever heard in Ireland, being heard in Counties Clare and Tipperary. Also destroyed were a number of tin boats intended to be used used as bridging material, the crater left by the explosion can still be seen.
