Harold Alexander vs Su Yu

As commander of the British 1st Corps, Alexander oversaw the evacuation of Allied troops from Dunkirk from May 26 to June 4, 1940. He organized the defense of the perimeter and ensured the orderly withdrawal of over 330,000 soldiers under constant German air and ground attack.

Alexander was appointed commander of British forces in Burma in March 1942. He led a difficult retreat from Burma to India as Japanese forces advanced, successfully preserving the core of the British Indian Army despite heavy losses and difficult terrain, preventing a complete collapse.

Alexander was appointed commander of the 15th Army Group in December 1943, responsible for all Allied ground forces in the Mediterranean theater. He directed the Italian Campaign, including the Anzio landings and the advance through central Italy, coordinating British, American, and other Allied units.

Alexander's forces captured Rome on June 4, 1944, after a hard-fought campaign that included the Battle of Monte Cassino and the Anzio breakout. The capture of the Italian capital was a significant psychological victory, though it came just two days before the D-Day landings in Normandy.

Alexander was appointed Governor General of Canada in 1946, serving as the representative of King George VI until 1952. He performed ceremonial and constitutional duties, including opening Parliament and representing the Crown in Canada, and was well-regarded for his diplomatic skills.

Su Yu was appointed commander of the East China Field Army (later the Third Field Army). He led this force in major campaigns against the Kuomintang, including the Huaihai Campaign, where his outnumbered forces achieved decisive victories through superior tactics.

Su Yu played a key role in the Huaihai Campaign, a major engagement of the Chinese Civil War. His forces encircled and destroyed a large Kuomintang army, capturing over 500,000 troops. This victory was crucial for the Communist takeover of eastern China.

Su Yu was purged during the Cultural Revolution, accused of being a 'capitalist roader' and a 'military revisionist'. He was removed from his posts and subjected to criticism, though he was later rehabilitated after Mao's death.
