He was in an Italian prison and escaped several times, the last successful one in September 1943.
He returned to England and gave good service as a commander soon after D Day in Normandy and was involved in several major operations, but unfortunately none which demonstrated the flair and success of Operation Compass.
Perhaps his two year imprisonment took the edge off him, or maybe he wouldn't have done any better if he'd never been captured. But I'm inclined to think that a couple of years as a POW deprived him of the opportunities to build on his success in Compass and to build on his command strengths. Nonetheless, his performance in Europe was still rather better than some commanders who hadn't suffered the privations of imprisonment.
I looked again and you were right, was imprisoned near Florence, sorry about that.
