A friend recently urged me to read Frank Kermode’s memoir Not Entitled – not for the account of a supremely successful academic career in the second half of the twentieth century, nor for insights into the making of a renowned literary critic, but for the account of his naval service. Kermode, I was told, had joined up in 1940. Isolated among madmen engaged on futile, conspicuously wasteful projects in Scotland and Iceland, his war experiences were a small, entertaining testimony to the ludicrousness of war.
