In December 1941 there were two raids. The first was Operation Anklet, a raid on the Lofoten Islands by No. 12 Commando on 26 December. The German garrison was in the midst of their Christmas celebrations and was easily overcome; the Commandos re-embarked after two days. Operation Archery was a larger raid at Vågsøy Island. This raid involved men from Nos. 2, 3, 4 and 6 Commandos, a Royal Navy flotilla, and limited air support. The raid caused significant damage to factories, warehouses, and the German garrison, and sank eight ships. After this the Germans increased the garrison in Norway by an extra 30,000 troops, upgraded coastal and inland defences, and sent a number of capital ships to the area.
