Groton — Redcoats and rebels clashed once again Saturday at Fort Griswold Battlefield State Park, to the sounds of musket- and cannonfire.

Only, these were reenactors at a commemoration of the 240th anniversary of the Battle of Groton Heights, when British soldiers, under the command of notorious turncoat Benedict Arnold, defeated a group of American patriots to take the hilltop fortifications on Sept. 6, 1781. The fort was defended by 165 Americans — 88 of whom died because of the battle, including their commander, Col. William Ledyard — against 800 British troops.

The event continues Sunday with a focus on the aftermath of the battle, including demonstrations of prisoner handling and an overview of 18th century medicine with demonstrations of surgical procedures used on battle casualties.
