That really is a most interesting letter. Thank you for posting it. While Dad's Army was a fun series to watch, behind it was the thought that is expressed somewhat in the letter. It was the spirit that I have always admired. In January 1941, the time in which the letter was written, England had been alone in carrying on a war against a superior foe in armament for well over a year. With the continent having fallen to Germany, it was still very much in the minds of the English that an invasion of their island could be expected. Nevertheless, they carried on with business as usual and preparing as best they could to defend their island. Outfits like the home guard made it clear that there was serious determination to stop anybody who would try to take England.
