Régiment La Sarre The Régiment La Sarre was a French Army regiment active in the 18th century . It is principally known for its role in the Seven Years ' War , when it served in the North American theatre . History . The regiment was recruited in the French region of Lorraine . After recruitment , most of the regiment left from Brest , France aboard a few French ships , such as Le Héros and Le Léopard . The last of the men would arrive in Quebec City on the 31st of May 1756 . They took part in the capture of Fort Oswego in August of that same year , and then escorted the British prisoners to Montreal after the battle . Régiment La Sarre played a key role in the victory at Fort Oswego losing 7 men in the process . In August 1757 , many soldiers of the regiment participated in the victory at Fort William Henry . At Fort William Henry , Régiment La Sarre contributed 800 - 900 men of the roughly 5000 who fought in the battle itself . The fort capitulated before they had a chance to launch a full on assault on it . The regiment then served under Louis - Joseph de Montcalm in 1758 at the Battle of Carillon . This victory was absolutely decisive for the French crippling a much larger British force . Régiment La Sarre also played a significant role in this battle . La Sarre was commanded by de Savournin during the battle . During the Battle , La Sarre took up the left flank along with the Languedoc regiment . The regiment lost a number of captains during the battle and perhaps took the heaviest French losses during the bloodiest and largest French victory of the war in North America . The regiment then participates in the battles of Montmorency , Plains of Abraham and Sainte - Foy . The Battle at Montmorency was another French victory in which Régiment La Sarre took part in . Le Noir a captain in the regiment , was noted to be extremely brave in this battle in particular . He lost half of his men and was shot , and still managed to survive . The next battle La Sarre took part in was the decisive English victory at the Planes of Abraham . About 50 men were either injured or killed from the regiment during the battle . The final North American battle which the regiment would take part in was the Battle of Sainte - Foy . This was another victory for the French and La Sarre , which was inconsequential to the outcome of the war . The regiment lined up on the left flank of the French lines . There were signs of retreat on the left , but the regiment fought bravely and held off the English forces for half an hour until the rest of the French army came to its aid . Eventually , La Sarre with the help of the rest of the French army , managed to push the enemy off the battlefield . After the Battle at Sainte - Foy , La Sarre took part in a halfhearted siege of Quebec City . On the 16th of May , the regiment was forced to lift the siege due to English reinforcements . In the months following the army was on a constant retreat , La Sarre took a few casualties along the way . A stray cannon shot took off a soldiers arm as well . The regiment was then charged to entrench themselves on Isle de Bourbon , but this was short - lived . Eventually the regiment met the same fate as the rest of the French presence in Canada . Regiment La Sarre was placed on English boats returning to France . On the 15th of September the Regiment would leave Canada never to return . Of the 31 officers in the regiment 11 were killed and the rest were at some point injured . The Regiment would meet again in 1763 deployed in various European campaigns .
