In a word [he writes], Henry V, so apposite in theme and spirit, as I and many others discovered, to the dispatch of a great expeditionary force in 1914, was actually written for a similar occasion in 1599 [the invasion of Ireland under the Earl of Essex]. Yet it would have been written in any case about this time, and the occasion was for Shakespeare a stroke of luck. . . . For the zenith of the play is not the victory—that is lightly passed over, and (in itself miraculous) is ascribed to God alone—but the King’s speeches before the battle is joined, the battle which all but the King think already lost. Every line of what Henry then says breathes the English temper, but one above all—

We happy few, we band of brothers.

If History never repeats itself, the human spirit often does: Henry’s words before Agincourt, and Churchill’s after the Battle of Britain, come from the same national mint.
