In short: Philippe de Hauteclocque was a French general who defied his government's 1940 armistice to join the Free French. To shield his wife and six children from potential Vichy retaliation, he adopted the nom de guerre Leclerc, a name that eventually became synonymous with the liberation of Paris and Strasbourg.

Born in 1902 into an old noble family with a long military lineage, Philippe de Hauteclocque graduated from Saint-Cyr in 1924. His early career included service in Morocco, where he was awarded the croix de guerre for leading goumiers in 1933. When Germany invaded France in 1940, he was captured, escaped, and eventually made his way to Britain to join General Charles de Gaulle. He adopted the name Leclerc to protect his family, a pseudonym he would legally incorporate into his name in 1945.

Leclerc's leadership was forged in the African desert. After securing French Equatorial Africa and Gabon for the Free French, he led a daring raid on the Italian outpost of Kufra in 1941. It was there that he and his men swore the Serment de Koufra, pledging to fight until their flag flew over the Strasbourg Cathedral. This promise drove his military trajectory, eventually leading to the formation of the 2e Division Blindée, an armored unit he meticulously built from diverse elements, including former Vichy forces and colonial troops.

The 2e Division Blindée became a central force in the Allied liberation of France. After landing in Normandy in August 1944, Leclerc’s division fought its way into Paris, accepting the surrender of the German commander Dietrich von Choltitz. He later achieved a tactical victory at the Battle of Dompaire before fulfilling his Kufra oath by reaching Strasbourg in November 1944. Despite his battlefield successes, Leclerc was a complex figure; he was known for his bluntness, his intense distrust of Vichy-associated officers, and his summary execution of French Waffen-SS prisoners in 1945.

Following the war in Europe, Leclerc was sent to command the French Far East Expeditionary Corps, representing France at the Japanese surrender in Tokyo Bay in September 1945. He recognized early that the conflict in Indochina required a political solution, yet his forward-thinking stance led to his recall in 1946. His life ended abruptly in an air crash in Algeria in 1947, leaving behind a legacy as one of France's most prominent military commanders of the twentieth century.
