I would like to think that if an invasion took place I would fight in some way. The last invasion that really got anywhere of mainland Britian was in 1066, so I guess the closest I can compare it to is the German occupation of Jersey. I also like to think that if I was alive in the 1930s, I would have been one of those people to volunteer to fight fascism in the Spanish Civil War as over 20 people in my 6th form college did.
