Hi Brenda
A long time since you originally posted this but only just discovered it.
Might I ask whether you were successful in tracking down the information you were after?
Just for the record, "Pitt Corner" was one of a string of British Army camps encircling the City of Winchester. The actual camp was mainly located in what is now "Oliver's Battery", indeed many of the roads in Oliver's Battery are actually the old army camp roads, and some of the first houses were converted army huts!
I had some trouble identifying a 217 Company Royal Engineers and tying it down to a Division who assembled near Winchester. Have you had any luck?
I am researching the army camps around Winchester, especially those on the Hursley Park estate (which includes Pitt) and I'd be very interested in any information you might have or wheter you would be prepared to share the images etc, with me for my research.
If you have any questions relating to Pitt Camp, please do feel free to ask and I'll do what I can to help.
Yours sincerely
Dave
