I noted with interest the Dublin Fusiliers' helmets in your picture by Rene Bull have a slightly darker (green?) pugaree and dome ventilator, and a paler (white?) stripe on the helmet above the pugaree.
So I think these POWs are probably not Dublins...
Could they be Durban Light Infantry, or men captured elsewhere?
I attach a photo of the memorial to those who fell, which I took when I first visited the site as a lad... in1969.
The past is not dead. In fact, it's not even past.
