JUNE 23-24--Combined elements of Air Force, Navy and Marine Corps virtually destroyed the electric power potential of North Korea with attacks on prime military targets which had been by-passed through almost 2 years of war. On the 23rd, the main effort was directed against the hydroelectric plant at Suiho, 40 miles up the Yalu River from Antung, Manchuria.

The attacks continued next day with more attention being given to the plants at Chosen, Fusen and Kyosen. This 2-day attack, which involved over 1,200 sorties, was the largest single air effort since the close of World War II and the first to employ planes from all the U.S. services fighting in Korea.
