Amid all the remembrance, Radio 3 came up with a simple yet effective way of reflecting on war’s impact. Threaded throughout the day on Sunday were ‘sonic’ memorials, three minutes of silence, or rather opportunities to stop and reflect. Not the music of a requiem mass, or a lonesome bugle, but the sounds of those places where the worst battles in recent history — from Antietam in America (during the Civil War) to Huaihai (between the Kuomintang and communists in China) via the Somme, Stalingrad and Afghanistan — were played out.
