General Mackesy lands 24th Brigade at Harstat, 37 miles North of Narvik. These regular Army troops are equipped for peaceful landings, not for offensive actions against German troops, & they will remain here while reserve troops see action around Trondheim. Lack of preparation characterizes all Allied landings in Norway.
British 148th Territorial (reserve) Brigade under the command of Brigadier Harold Morgan has been waiting for 2 days at Rosyth, on cruisers HMS Galatea & Arethusa and a transport ship destined for Namsos. They are ordered to Åndalsnes instead, to form a southern pincer for the advance on Trondheim. They disembark & board cruisers HMS Carlisle & Curacoa, losing anti-aircraft guns, ammunition & half a battalion (due to lack of space on the cruisers). They do manage to keep their now-useless maps of Namsos.
British 15th Brigade is en route to Norway, having been withdrawn from British Expeditionary Force (they left France on April 15).
Torpedo duel between U-3 and British submarine HMS Porpoise 10 miles southwest of Egersund, Norway. Neither sub is damaged.
