Pierre de Rigaud, marquis de Vaudreuil-Cavagnial

Pierre de Rigaud de Vaudreuil de Cavagnial, marquis de Vaudreuil (22 November 1698 – 4 August 1778 ) was a Canadian-born colonial governor of French Canada in North America. He was governor of French Louisiana (1743–1753) and in 1755 became the last Governor-General of New France. In 1759 and 1760 the British conquered the colony in the Seven Years' War (known in the United States as the French and Indian War).

Life and work
He was born to the Governor-General of New France, Philippe de Rigaud Vaudreuil and his wife, Louise-Élisabeth, the daughter of Pierre de Joybert de Soulanges et de Marson, in Quebec. He was the uncle of Louis-Philippe de Vaudreuil.

Commissioned an officer of the French army while still a youth, in 1733 he was appointed governor of Trois-Rivières, and in 1742 of French Louisiana, serving there from to May 10, 1743 to February 9, 1753 and proving himself a skilled officer and capable administrator. While governor of Louisiana, he married Jeanne-Charlotte de Fleury Deschambault, a widow about 15 years his elder.

He moved to France in 1753 before being appointed by King Louis XV as governor of New France in 1755.

Although Vaudreuil held supreme civil authority in Canada and was technically commander-in-chief of all French forces there, he clashed often with Montcalm, the military commander in the field, who resented his oversight role. The two men grew to detest one another, much to the detriment of the French war effort.

After Montcalm lost to the British forces under Maj. Gen. James Wolfe at Quebec City in the Battle of the Plains of Abraham, Vaudreuil tried to rally resistance to the British but to no avail. He was forced to surrender Montreal on 8 September 1760 to Maj. Gen. Jeffrey Amherst.

One of several scapegoats for France's losses in the New World, Vaudreuil was imprisoned in the Bastille on March 30, 1762 but was released on May 18. He was joined by Bigot, Cadet, Pean, Breard, Varin, Le Mercier, Penisseault, Maurin, Copron, and others. Of the 21 men brought to trial, 10 were condemned, six were acquitted, three received an admonition and two were dismissed for want of evidence. Absent were 34, of whom seven were sentenced in default, and judgement was reserved in the case of the rest. Exonerated in a military tribunal held in December 1763, he was awarded a pension and military decoration.

After selling his Canadian seigneuries at Vaudreuil and Rigaud to his cousin, Michel Chartier de Lotbinière, Marquis de Lotbinière, he retired to his ancestral estate near Rouen, although the episode ruined his fortunes. He died in Paris on 4 August 1778.

His nephew Louis-Philippe de Vaudreuil was the second in command of the French naval units supporting the Americans during the American Revolution. He was present at the defeat of the British fleet by the French at the pivotal Battle of the Chesapeake during the siege of Yorktown in 1781, although he was later defeated by the Royal Navy at the Battle of the Saintes.

Vaudreuil was one of three governors-general of Canada known to have owned enslaved people. During his tenure, he owned 16 people, 13 of whom were Africans.

In Literature
Vaudreuil is a menacing offstage presence in Kenneth Roberts' Arundel novels, Arundel and Rabble in Arms.
