The Battle of Jersey was fought in January 1781 when a French expedition sought to capture the strategically significant island of Jersey, part of the Channel Islands in the English Channel. The operation was led by François de Grimaldi, aiming to exploit what was perceived as British military vulnerability during the American Revolutionary War. The French landed near St. Helier and sought to take control of key points on the island, hoping that a swift takeover would destabilize British presence in the region. In response, British forces, commanded by Major Francis Peirson, quickly organized a counter-offensive to protect their territory. A fierce engagement ensued, characterized by approaching skirmishes and direct confrontations. British troops launched a surprise attack against the French positions, leading to intense fighting within the streets of St. Helier. The battle resulted in significant casualties on both sides, but ultimately, the British emerged victorious, with Major Peirson playing a crucial role in organizing the defense and leading his men courageously. The battle concluded with Grimaldi's retreat, marking a critical moment when the last significant attempts by France were thwarted in their efforts to invade Jersey, which subsequently remained firmly in British control during the Revolutionary period.
