  • The Norwegian government declared war on Germany after several days of fighting. On the same day, German troops advanced past Oslo, but were held up by Norwegian forces north of the city in the village of Bagn. The British 148th Brigade arrived in Ã…ndalsnes overnight; commanding officer Brigadier Morgan was given conflicting orders, one ordering him to march north to Trondheim, while the other ordered him to march south to support Norwegian troops in the Gudbrandsdal and Østerdal valleys north of Oslo. Meanwhile, troops of the German 181st Infantry Division began to arrive at Trondheim as reinforcements via aircraft, transport ships, and submarines. ww2dbase [Invasion of Denmark and Norway | TH]
