PIP RIDGE DEFENCES 1 2 3 and 4

[Sgt Stripes]

Hi I am studying the attack on PIP RIDGE that took place on Sep 18 1918. Dose anyone have any aerial photographs taken of the Bulgarian defences on PIP RIDGE or any information of what the defences consisted off. At first I thought that each hill stroke PIP , was simply rock cut trenches but I now understand that the defences were more of fortified machine gun nest with bunkers covered with barbed wire. I would like to hear of any reports from men who after the Bulgarian retreat went up on the ridge and described what they found.   Many Thanks
