Battle of the Atlantic: 75th Anniversary Movie Poll

The Battle of the Atlantic has been called the "longest, largest, and most complex naval battle in history." The campaign lasted nearly six years from September 1939 until May 1945 and operationally covered a fifth of the earth's surface. Its engagements numbered more than a thousand during 100+ convoy crossings, as well as about another thousand in single-ship encounters. The human toll was probably the greatest of the war on both sides with a loss of more than a 100,000+ lost souls. Also staggering were both the material loss of much needed war supplies and the sinking of 5000 ships. 2020 marks the 75th anniversary of the battle's conclusion with its latest movie depiction, USS Greyhound: la bataille de l'Atlantique (2020), added to the interesting sub-genre.
