Fort New Richmond

Fort New Richmond was built by the British in 1779 on the east bank of the Mississippi River in what was later to become Baton Rouge, Louisiana. The Spanish took control of the fort in 1779 and renamed it Fort San Carlos.

History
The fort was built by Lieutenant-Colonel Alexander Dickson (British Army commander of the Baton Rouge area) after he discovered that Fort Bute (built in 1765) was indefensible against cannon. The fort at Baton Rouge was built on the Watt's and Flowers Plantation and was completed during the six weeks preceding hostilities in the area during the American Revolutionary War. The fort consisted of a ditch eighteen feet wide and nine feet deep surrounding an earthen wall with pallisades in the shape of a Chevaux de frise. It was armed with thirteen cannon, four hundred regular British soldiers from the 16th and 60th Regiments of Foot, a company of grenadiers from Waldeck and an estimated 150 Loyalist Militia.

The fort was captured on September 21, 1779 when Bernardo de Gálvez, the colonial Governor of Spanish Louisiana, after capturing Fort Bute led his force of 1,427 men against Baton Rouge. The surrender of Fort New Richmond cleared the British out of the Mississippi River estuary area.
