During the last decade of his life he wrote some of his best works, including the "Symphonic Fantasia '1912"' (also called "Symphony No. 5"), the "Ode on the Nativity" (1912), "Jerusalem" (1916) and the "Songs of Farewell" which includes the song “My Soul, there is a Country”. These were songs about the needless suffering in the war. He died of influenza in Rustington, Sussex.
