That series of photos was taken across the street from what is now the Mayor's office
in the town of Notre Dame de Cenilly, France. This is southwest of St Lo, on the D38 road and the prisoners were standing in front of the local haberdashery, being searched by Lt. Paul Unger of the 2nd Armored Division MP Company Unger was over 6 ft tall himself, but these giant SS prisoners made him look small in comparison. This info was published in my 3rd book now out of print, entitled 'Breakout at Normandy-The 2nd Armored Division in the Land of the Dead' (MBI pub. 1999). A new edition is planned with updates and additional photos-it should be out around Christmas time from Casemate pub.
Btw, I spoke with and visited the family of the late Lt. Unger in the 1990s and the MP armband he wears in the photo has been in my collection ever since. Unfortunately, he did not keep any SS souvenirs, but I did get an IC 2d class and some other common Nazi stuff from his family.
