The  Kriegsmarine  auxiliary cruiser  Thor  was raiding in the mid Atlantic in early 1941. On that cruise, the Germans engaged two other British armed merchant cruisers (HMS  Alcantara  and HMS  Carnavon Castle ) in surface battles but they ended indecisively. So when  Thor  encountered HMS  Voltaire , her crew were already battle tested and anxious to sink an enemy combatant.  Thor  was 122 m (400 ft 3 in) long and weighed 9,200 long tons (9,300 t), she was armed with six 150 mm (5.9 in), two 37 mm (1.46 in) and four 20 mm (0.79 in) naval guns along with four 533 mm (21.0 in) torpedo tubes. The raider also carried an Arado Ar 196A-1 floatplane for reconnaissance and had a complement of 349 officers and crewmen.[1]
HMS  Voltaire  was larger than the raider—displacing 13,245 long tons (13,458 t)—but with a smaller crew of 269 men and officers. She had eight 152 mm (6.0 in) and two 76 mm (2.99 in) naval guns, including at least one anti-aircraft mount.  Thor  was returning to Germany when she found  Voltaire  heading to Freetown about 900 mi (780 nmi; 1,400 km) southwest of the Cape Verde Islands.[1]
It was about 06:15 on 4 April when crewmen of  Thor  spotted smoke on the horizon. Captain Otto Kähler assumed the vessel to be a coal burning ship so he altered course into the direction of the smoke. When the Germans were able to make visual contact with HMS  Voltaire , they suspected she was a neutral ocean liner as she did not attempt to escape. The British—under Captain J.A. Blackburn—sighted the approaching Germans coming head on, so they fired a burst of anti-aircraft fire as signal for identification. A signal from  Thor  was not returned, but the British soon discovered the identity of the approaching ship at about 06:45, when it replaced the flag of Greece with a German naval ensign and fired a shot across  Voltaire ‍ '​s bow. The British responded by manning their guns and firing a broadside with their mixed armament, but to no avail; they were outgunned and outranged.[1]
After only four minutes of dueling at around 9,000 m (9,800 yd) away, the Germans began striking  Voltaire  with their 150 mm (5.9 in) guns. The first shots entered the radio room and the generator room of  Voltaire , heavily damaging the vessel, knocking out communications and steering gear and putting her into a list. Heavy fires also broke out and nearly covered the entire deck of the British ship. Despite the fire the Royal Navy gunners continued fighting for nearly an hour. For the next several minutes, the two sides fired; only one British shot managed to hit  Thor , and it caused no casualties, the shot tearing off some radio equipment attached to the main mast. By 07:15, only two of the British 152 mm (6.0 in) guns were in action, while  Thor  circled around  Voltaire , firing rapidly.[1]
At 08:00, the German's 150 mm (5.9 in) guns overheated so Captain Kähler decided on a torpedo attack to end the engagement. But just as  Thor  was lining up to fire a spread, a white flag was observed aboard Voltaire  and so the firing ceased. Captain Blackburn—having lost 72 men killed in action—gave the order to abandon ship and for the next five hours the Germans rescued 197 survivors, two of whom died later on and the rest became prisoners of war. Kähler also recorded that half of the rescued sailors were wounded. After the battle,  Thor  continued on to Germany to refit for a second raiding voyage. She had fired 724 rounds in a 55 minute battle, more than 50 percent of her ammunition.[1]
