This is a private letter written by General Montgomery, Commander of the Allied ground forces, to General William Simpson, in charge of the US Ninth Army on "D-Day."
Simpson is pictured 2nd from the right in the picture, standing next to Montgomery in the centre.
When was the letter written? How soon after "D-Day"?
What did Montgomery mention first in this letter?
Did Montgomery regard the Operation as a success or failure?
What fears did Montgomery still have for the future?
