E-Boats were German versions of the American PT boat. They were a little faster at 50 knots and could travel much farther, 700 miles. In 1944, a squadron of E-Boats came across undefended American and British troops practicing for D-Day and launched an attack, killing 1000 American soldiers and a few Brits. In 1956 the British used captured E-boats manned by the same German crews to launch spy missions against the Soviet Union. No E-boats survive today but they were a masterpiece of design.
"Two Coast Guard-manned LST's open their great jaws in the surf that washes on Leyte Island beach, as soldiers strip down and build sandbag piers out to the ramps to speed up unloading operations." 1944.
