28 June 1940, German bombers attack the town and harbour of St Peter Port, Guernsey. Misidentifying a row of trucks containing tomatoes for military vehicles they destroy them killing 33 civilians in the process, luckily just over a week earlier many of the islanders had been evacuated. Just two days later the island is under German occupation. For the next five years those remaining would live alongside their occupiers - one soldier to every two civilians - as Hitler ordered the island to be turned into an ‘impregnable fortress’.
