On 10 May 1941, Hess made a solo flight to Scotland, where he hoped to arrange peace talks with the Duke of Hamilton, whom he believed to be a prominent opponent of the British government's war policy. The British authorities arrested Hess immediately on his arrival and held him in custody until the end of the war, when he was returned to Germany to stand trial in the Nuremberg Trials of major war-criminals in 1946. During much of the trial, he claimed to be suffering from amnesia, but he later admitted this was a ruse.
