Dunkirk was a “close-run thing” but a wonderful thing all the same. Imputing any kind of charitable behavior on the part of the Germans is some form of low humor. The concept of “Glory” in war is silly and a backwards look intended to make the victors feel better about the horrors they survived. There is “nobility” in defending against an aggressor (none for the aggressor, however) but it is cold comfort for those who died and for those who receive telegrams at home. How can we do otherwise but praise those who persisted in our defense?"How is sneaking away from retreat anything but an inglorious manoeuvre"
That is just laughable, glory had nothing to do with the matter, the Germans had won the battle for France and all the British had left to do was to withdraw as many of their men as they could, to prevent them from being captured and to have an army to be able to fight in the future. Neither diplomacy nor war has anything to do with "glory", it is always the matter of making the best of the situation in the circumstances in which those who are negotiating or fighting find themselves.
