A somewhat interesting article on the Bomber Command bases in the Midlands and north east of England - including RAF Station Grimsby. The limited info on Grimsby mentions some information I have not come across before. It says that in April 1945 the base was no longer deemed operational due to the runways being deemed unsafe. The data shows that 116 Lancasters and 48 Wellingtons were lost flying from Waltham.
As and when information is found I'll post to this blog.
