マシュー・リッジウェイ
During 1951, as the war turned against the United States, the Chinese and North Koreans made vague allegations of biological warfare, but these were not pursued. General Matthew Ridgway, United Nations Commander in Korea, denounced the initial charges as early as May 1951. He accused the communists of spreading "deliberate lies". A few days later, Vice Admiral Charles Turner Joy repeated the denials.
