“Had the BEF not returned to this country,” General Brookelater wrote, “it is hard to see how the Army could have recovered from the blow.” That was the practical significance of Dunkirk. Britain could replace the 2,472 lost guns, the 63,879 abandoned vehicles; but the 224,686 rescued troops were irreplaceable. In the summer of 1940 they were the only trained troops Britain had left. Later, they would be the nucleus of the great Allied armies that won back the Continent. The leaders—Brooke, Alexander, and Montgomery, to name only three—all cut their teeth at Dunkirk.
