This monument was erected under the patronage of the State of Connecticut in the 55th year of the Independence of the U.S.A. in memory of the brave patriots massacred at Fort Griswold near this spot on the 6th of Sept. AD 1781, when the British, under the command of the Traitor Benedict Arnold, burnt the towns of New London and Groton and spread desolation and woe throughout the region.
Benedict Arnold (January 14, 1741 [O.S. January 3, 1740] – June 14, 1801) was an American-born British military officer who served during the American Revolutionary War. He fought with distinction for the American Continental Army and rose to the rank of major general before defecting to the British in 1780. General George Washington had given him his fullest trust and had placed him in command of West Point in New York. Arnold was planning to surrender the fort to British forces, but the plot was discovered in September 1780, whereupon he fled to the British lines. In the later part of the war, Arnold was commissioned as a brigadier general in the British Army and placed in command of the American Legion. He led British forces in battle against the army which he had once commanded, and his name became synonymous with treason and betrayal in the United States.
Born in Connecticut, Arnold was a merchant operating ships in the Atlantic when the war began. He joined the growing American army outside of Boston and distinguished himself by acts that demonstrated intelligence and bravery: In 1775, he captured Fort Ticonderoga. In 1776, he employed defensive and delaying tactics at the Battle of Valcour Island on Lake Champlain that gave American forces time to prepare New York's defenses. His performance in the Battle of Ridgefield in Connecticut prompted his promotion to major general. He conducted operations that provided the Americans with relief during the Siege of Fort Stanwix, and key actions during the pivotal 1777 Battles of Saratoga in which he sustained leg injuries that put him out of combat for several years.
