Churchill said this on October 29, 1941, when he visited Harrow School. It was after the Blitz and things were looking up a bit for Britain. Here is the relevant part of the speech: But for everyone, surely, what we have gone through in this period--I am addressing myself to the School--surely from this period of ten months, this is the lesson: Never give in. Never give in. Never, never, never, never--in nothing, great or small, large or petty--never give in, except to convictions of honour and good sense. Never yield to force. Never yield to the apparently overwhelming might of the enemy. Reference:
