“Only a few days after this picture was made, the tank and monument was blown up during the night. “

There is an interesting story about that monument.
My Father lived to be 90 but his last year was in a nursing home. At times he would be fairly normal and at other times he did not recognize his children.
Thinking it might jog his memory, I brought a bunch of his WWII pictures and was showing them to him. When he saw that tank he definitely seemed to have a lucid moment. He sort of laughed and said that it was blown up by the combat engineers.
Of course that might not mean a thing and I had never heard him say that before.
