1943 Filipstad explosion

The 1943 Filipstad explosion was a fire in an ammunition store at Filipstad in Oslo on Sunday, 19 December 1943, during the occupation of Norway by Nazi Germany. The fire started during the unloading of ammunition from the transport ship Selma. The estimated amount of exploded ammunition varies from 800 to 1,200 tons. A large number of shells and grenades were tossed into the air and spread over the city. There were around 40 Norwegian casualties and around 75 Germans were killed, and 400 wounded. About 400 buildings were severely damaged.
The first explosion occurred at around 14:30 local time, and killed 20 dock workers, two crane operators, several German guards and crew from Selma. Workers that were not killed immediately managed to escape from the area or find shelter among large cement blocks on the wharf. The main explosion occurred two hours later, at around 16:30, when an estimated 400 tons of ammunition exploded within a few seconds, five firefighters were killed and sixteen severely injured. The explosive fire lasted several hours. The dangerous situation was declared over at 21:45 the same night. A nearby coal store of 20,000 tons had been set on fire and burned for three weeks. The ship Selma did not explode during the Filipstad fire. The ship was towed away from Filipstad. It exploded and sank in another explosion on 11 January 1944.
