Passage: Rodney was damaged by German aircraft at Karmoy, near Stavanger on 9 April 1940, when hit by a 500 kg (1,102 lb) bomb that pierced the upper deck aft of the funnel, but did not explode and exited sideways after striking the armoured deck. On 13 September, she was transferred from Scapa Flow to Rosyth with orders to operate in the English Channel when the German invasion of Britain was expected. In November and December, Rodney was assigned convoy escort duties between Britain and Halifax, Nova Scotia. In January 1941, Rodney joined the hunt for the German capital ships Scharnhorst and Gneisenau, without success. On 16 March, however, while escorting a convoy in the North Atlantic, contact was made with the German battleships, but no battle followed, as the German ships turned away when they realised that they were facing superior firepower.

Question: Which ships did Rodney search for in 1941?
Scharnhorst and Gneisenau
