In the practice of international law, command responsibility is the legal doctrine of hierarchical accountability for war crimes, whereby a commanding officer (military) and a superior officer (civil) is legally responsible for the war crimes and the crimes against humanity committed by his subordinates; thus, a commanding officer always is accountable for the acts of commission and the acts of omission of his soldiers.
Command responsibility: the war criminals of the world are tried, judged, and sentenced by the International Criminal Court at The Hague, Netherlands.

Tomoyuki Yamashita was a Japanese convicted war criminal and general in the Imperial Japanese Army during World War II. Yamashita led Japanese forces during the invasion of Malaya and Battle of Singapore, his conquest of Malaya and Singapore in 70 days earned him the sobriquet "The Tiger of Malaya" and led to the British Prime Minister Winston Churchill calling the ignominious fall of Singapore to Japan the "worst disaster" and "largest capitulation" in British military history.
Yamashita was assigned to defend the Philippines from the advancing Allies later in the war. Although he was unable to prevent the superior Allied forces from advancing, despite dwindling supplies and Allied guerrilla action, he was able to hold on to part of Luzon until after the formal Surrender of Japan in August 1945.
