After WW2 actions

[Garry Shipton (RIP)]

this may be a dumb question but do any of our historians out there have any published info of helping concentration camp prisoners.The 1st div service corp trucks were convoyed ,for what reason,I don't know,across the German border to aid these victims.I do remember my father telling me of the horrors they saw when they got to the camp,this camp also I could't name.
Thanks
