My wife's father, Peter John (Wolf) Cooper, 1922-1972, was one of the lads who volunteered to go and help protect Finland from Russian invasion in 1939. Unfortunately, the conflict ended before they became fully involved but after they had arrived in Finland. As a result, they spent several years stranded in Finland and Sweden before eventually being able to make their way home. He is mentioned very briefly in Justin Brooke's book, 'The Volunteers' but we don't know too much about what he did there (apart from meeting and marrying my wife's mother in Sweden) or why he is referred to as 'Wolf' in the book. Does anyone else have family members who were involved in this endeavour or any information relating to this?
