Salvation lay here, in America. The green and feeble U.S. Army of just a few years earlier now exceeded 6 million, led by 1,000 generals, 7,000 colonels, and 343,000 lieutenants. The Army Air Forces since mid-1941 had grown 3,500 percent, the Army Corps of Engineers 4,000 percent. A Navy that counted eight aircraft carriers after Pearl Harbor would have fifty, large and small, by the end of 1943.
