The Coast Guard Compass has an excellent post on one Coast Guardsman’s perspective as he experienced the landings on the beaches of Normandy in 1944. The Coast Guard historian has a very comprehensive index of information and stories related to the invasion available on the historian’s website.
Coast Guard participation in the invasion included three Coast Guard manned attack transports, two more that were partially CG manned, eleven Landing Ship Tanks (LST), 24 Landing Craft Infantry, Large (LCI(L)), and 60 wooden hulled 83 foot patrol boats. In addition the Coast Guard manned numerous smaller landing craft.
