We March Against England

"In May 1940 Nazi Germany was master of continental Europe. The only European power still standing was Great Britain--and the all-conquering German armed forces stood poised to cross the Channel. After the RAF fighter forces had been destroyed, the Channel swept of mines, and the Royal Naval defenders worn down, two German army groups were set to storm the beaches of southern England. Despite near-constant British fears from August to October, the invasion never took place, first being postponed to spring 1941 before finally being abandoned entirely."--Amazon.com
