V1
Walking in a street leading into Lower Sloane Street yesterday, I walked past an inscription on a wall. It took a second to filter into a mind in neutral, so I walked back inscription carved into a large stone set in the wall and read of the 74 US Military personel and 3 civilians (I think the numbers are right) that were killed by a V1 Flying Bomb nearby. I forget the date but it just seemed rather incongruous coming across it out of the blue.
I have never seen any other similar memorial in London but perhaps I've never looked.
