My Uncle's AT(Anti-Tank) UNIT consisted of four guns attached to the regimental HQ and deployed to support infantry. Their 57mm towed AT guns were overrun by counter attacking Panthers and supporting German infantry. The range a 57mm could penetrate a panther's frontal armor was very, very close. They did disable two and kill three panthers with Flanking shots but others rolled right over their position. The Nazis raked what was left of them with MG and small arms fire. I guess they were in no mood to take prisoners. The two survivors must have been left for dead. Hope this explains the situation lwd.
