German bombers destroyed much of the wood-constructed town on April 20. Attacks lasted throughout the day and most of the wood houses, as well as the railway terminal, a church, the French headquarters and the two wooden wharves were burned. The stone wharf was damaged. The Norwegians paid dearly for the help the Allies brought. Fortunately, only one Allied ship was present in the harbour when the attack occurred. Fourteen German bombers went after the tiny anti-submarine trawler, HMS Rutlandshire, and badly damaged it just down the bay from Namsos. The ship was beached and the survivors were machine gunned in the water.
The British felt the need to provide protection from submarine attack for their ships entering and leaving Namsos. Lacking air cover, the small, slow anti-submarine sloops and trawlers used were very vulnerable to air attack. On April 30th, the sloop HMS Bittern was sunk by Junkers Ju 87 dive bombers off Namsos. On May 1st, three British anti-submarine trawlers at the entrance to Namsfjordwere destroyed by aircraft, the latter managing to make it back to Namsos where she burned.
The Norwegian air force had no units in the vicinity. The only Allied air presence to counter the Luftwaffe was during the first British landings. A brief patrol was mounted well offshore by several obsolete biplane fighters, Gloster Gladiators, operating from the aircraft carrier, HMS Glorious. They claimed three German planes shot down. Some eighteen Gladiators were flown off the Glorious and operated from the frozen Lake Lesjaskog, but these were too far south to help Namsos. The Luftwaffe (literally, air weapon, pronounced looft-vaaf-feh) is the air force of Germany.
General De Wiart received orders on April 28 to evacuate Namsos, and on April 29, an evacuation convoy of destroyers, three British and one French, left Scapa Flow in Scotland under the command of Lord Louis Mountbatten. A larger naval force followed at a distance to protect them against attack by German battlecruisers. They were bombed on May 1st as they crossed the North Sea. That evening they encountered thick fog 40 miles short of their rendevous point at Kya Lighthouse, which was forty miles by sea from Namsos. Plans to evacuate that night had to be cancelled. Meanwhile German troops were closing in on the rearguard in the hills outside Namsos, and the convoy ships were vulnerable to air attack if the fog lifted in daylight.
Rather than wait for the evening, Mountbatten took his ships in on May 2, moving from fogbank to fogbank. This was a very dangerous enterprise on a rocky coast. Despite the fog, the ships were bombed. The ships' masts were sticking out above the fog, giving the German bombers an approximate target. When they reached Namsos, the fog lifted, revealing a burning town and swarms of German bombers. Since it would have been suicidal to enter in these conditions, the British ships ducked back into the fog and returned down the bay.
The next day, May 3rd, the last possible for evacuation, dawned as foggy as before. Admiral Sir Andrew Cunningham, in overall command of naval forces in the area, screened the evacuation convoy with two cruisers and four destroyers at Kya Light and sent the cruiser, HMS York, five destroyers and three transports in. Mountbatten led in HMS Kelly at 26 knots as the sun was going down. When they rounded the last bend of the fjord they saw Namsos on fire. Mountbatten at this point did not know if the Germans were in possession of the town. A burning anti-submarine trawler, HMS Aston Villa, lay just ahead. As he closed the wharves, Mountbatten could see that everything was ablase. But, Carton De Wiart was there with 5,500 troops lined up in good order, waiting to get off.
Evacuation began at 10:30 pm. Two of the transports were able to get alongside the damaged quay and filled up with troops. The destroyers took off the other men and ferried them to the York and the third transport, before taking a last load themselves. Meanwhile the rearguard was engaging the Germans to cover the evacuation. A tricky disengagement followed and a rush for the last ship, HMS Afridi. There was no time to destroy supplies left on the wharves, so the Afridi shelled the equipment as she pulled away from Namsos. It was 2:20 am, May 4th.
They knew to expect trouble when day broke and the German bombers sought them out. At 4:30 am the rear of the British convoy was sighted by German reconnisance aircraft and bombers soon followed. The force was attacked continuously until late afternoon.
During the third attack of the day the French destroyer, Bison, was hit in the foreward magazine and exploded with 136 killed. The other destroyers turned back to pick up survivors who were being machine gunned in the water. After the Afridi had picked up some of the French sailors and Allied soldiers, she was hit by two heavy bombs and capsized with the loss of a hundred men, including some of the rearguard, the wounded from the Bison and survivors of the HMS Rutlandshire.
British anti-aircraft fire destroyed a number of German aircraft. The convoy reached Scapa Flow on May 5th...
