Action in the North Atlantic is a 1943 American war film directed by Lloyd Bacon, featuring Humphrey Bogart and Raymond Massey as sailors in the U.S. Merchant Marine in World War II.
During their brief liberty, Steve spends time with his wife Sarah Ruth Gordon, while Joe meets and marries singer Pearl ONeill Julie Bishop. The film cuts to the union hall where merchant seamenincluding the survivors of Jarvis last shipspend their time waiting to be assigned to a new ship. Over a round of poker, Johnnie Pulaski Dane Clark jokes about getting a shore job. When pressed by other seaman, Pulaski reveals his fear of dying at sea. The others shame him into signing along with them for another ship. Another sailor, Alfred Boats OHara Alan Hale, Sr., is tracked down by his wife, whom hes apparently not seen since being rescued. She angrily serves him with a summons. OHara, knowing hes headed back to sea, gleefully tears the summons up, saying them Liberty Ships are well named. Then it is back to sea on a new Liberty ship, the SS Seawitch, on a convoy carrying vital war supplies to the Soviet port of Murmansk.Convoy 211 is attacked by a wolfpack, a group of German Uboats that hunt for convoys. There are losses on both sides, but the convoy commander is forced to order his ships to disperse. One persistent Uboat chases after the Seawitch, but cannot get close because of the ships guns. During the night, The Seawitch eludes the sub by shutting down its engines to prevent sonar detection. The Uboat contacts the Luftwaffe, and the next day, a pair of Heinkel He 59 seaplanes find the freighter and attack. Several seamen are killed and Steve is shot in the leg, before both planes are shot down, the second plane crashing into the bow. Joe takes command. The Uboat sights the ship again and hits her with a torpedo. Joe orders the men to set fires and make smoke so that it appears as if the ship is sinking. When the submarine surfaces to finish her off, the Seawitch rams and sinks it. A squadron of Russian planes escorts the Seawitch, with its valuable cargo intact, into Murmansk to a warm Russian welcome. ........
