My mother was born in Jersey and was there during the occupation. I think she would not give away a weapon too easily now. Her family all made it through the war unscathed, just! Unlike a couple of families she knew from school which in hindsight she thinks must have had Jewish blood. The Channel Islands have a long history of invasion and I think would know the value of a good weapon.

Have you seen the brief “Island at War” British TV series about the WWII experiences there?
