Hi

I'm new to the forum and was hoping that someone may be able to help me or point me in the right direction. I'm starting to research my uncle, Sergeant Lawrence Henry Nicholson 1353479 who was an air gunner serving in 149 Squadron.He died on 21/08/1942. I'm not sure where to start. I'm planning on sending for his service record but is there a squadron war diary or history that I could get?

Thanks in advance

Dave
