I’m pretty sure gaunty was referring to the blokes going the other way four years later, almost to the day, with a serious bit of payback on their minds, Meeb.
And yes, Algy B, you’re quite right, it was June 6th 1944, not 1945. But I suspect gaunty wasn’t having problems with remembering whether it was ‘44 or ‘45, but if he’s anything like me, what year this is now!
