Found the following article online, use it to answer the question: Who was commissioned to compose a score for the 1969 film, Battle of Britain?  In 1956 Walton sold his London house and took up full-time residence on Ischia. He built a hilltop house at Forio and called it La Mortella. Susana Walton created a magnificent garden there. Walton's other works of the 1950s include the music for a fourth Shakespeare film, Olivier's Richard III, and the Cello Concerto (1956), written for Gregor Piatigorsky, who gave the premiere in January 1957 with the Boston Symphony Orchestra and the conductor Charles Munch.
