Marquis de Choisy

Brig. Gen. Claude Gabriel marquis de Choissey (French: ) was at the siege of Yorktown in command of Lauzun's Legion and Gen. George Weedon's Virginia militia, at Gloucester, Virginia, under the command of Rochambeau, opposite Banastre Tarleton.

France was allied with Poland against Russia, in the Bar Confederation. On 2 February 1772, he led 270 men, in the capture of Kraków Poland, from 1,500 Russians. A small party entered through a sewer, surprised the guard, and opened the postern gate. Not being reinforced in time, they retreated to the citadel, Wawel Castle. They held it through a siege of several weeks against 18,000 Russians, until it fell to Suvorov on 28 April 1772.

On 24 March 1772, he was appointed Brigadier General of Infantry, and in 1779 appointed to be Mestre of the Camp for the Fourth Regiment Chasseurs a Cheval.

Competition was fierce among French officers to join the expedition to America, to gain fame and promotion. Marquis de Choisy arrived at Brest with five others officers to join the Army, but was turned away. Then he sailed, with ten officers, on the Sybille for Santo Domingo, changing ships to La Gentille, arriving at Newport on 29 September 1780.

Tensions ran high among officers in camp; he sought to reconcile officers who had fought a duel.

On 29 October, Rochambeau sent Brigadier General Choisy with Lauzun's Legion, as they marched from Rhode Island to Head of Elk, Maryland, traveled by water to Alexandria, Virginia, and marched to Glouchester Courthouse.
