Love him or hate him, Churchill did the business during the war.
Let's get back to Winston Churchill.
I have been thinking about this comment of yours, LR, in connection with your home island of Guernsey.
One of the saddest aspects of the latter part of WW2 was the decision to leave the Channel Islands under German occupation while the rest of Europe was being freed. It is ironic that a few months after D-Day that the whole of France had effectively been liberated but no attempt was made to relieve the situation in these tiny pockets of British life.
Chruchill's policy appears to have been to starve the occupying Germans into submission. The only method of access remaining to the Germans was by U-boat. The occupying forces could probably have been quickly overcome by a series of focused attacks. But instead women, children and old men (the young and fit men had left to join the armed forces) were increasingly having to allow the German occupiers to plunder their food stores. Eventually, there were Red Cross supplies delivered by the SS Vega.
Eventually, the Channel Islands were liberated. But liberation did not take place until
after WW2 in Europe had ended. The day after, in fact. Germany had signed the articles of surrendered but was still occupying Jersey, Guernsey and the other islands.
And what appears to be even more bizarre, following liberation some German soldiers were drafted into the islands' police forces as temporary policemen until returning demobilised islanders could take over.
