Metcalf was educated at Chefoo School, the China Inland Mission school in Yantai, Shandong Province. On 5 November 1942 the school was closed by the Japanese occupying army and the staff and pupils interned in an American Presbyterian mission compound on Temple Hill, Yantai. Metcalf was amongst those interned and had no contact with his parents and his elder sister, Ruth, until his release in 1945. While in this POW camp, Metcalf made a Christian commitment. In September 1943 the Temple Hill civilian internment camp was closed and the internees moved to another camp at Weihsien, Shandong Province. At Weihsien, Metcalf was befriended by Eric Liddell, the Olympic medallist, and greatly influenced by Liddell's attitude to the Japanese to pray for his captors. Just prior to his death Liddell gave Metcalf, a keen runner, his running shoes. Metcalf was a coffin bearer at Liddell's funeral in the camp in February 1945 and at the ceremony committed himself to serve as a missionary in Japan. The Weihsien civilian internment camp was liberated on 17 August 1945.
