The Volkspark Houses.
Smudge,
It's a moot point. I don't know at what date the Volkspark was handed back to the German State (or the Municipality of Cologne), but I never heard of it happening up to the time we left RAF(G) in Autumn '62.
By then, the original "Force of Occupation" idea was long out of the window; we were all pals in NATO now, facing the Tartar hordes together. I cannot think that the Germans were resolved to extinguish all traces of our sojourn in their green & pleasant land (even if we'd been uninvited guests in the first place).
And the fact that they had designed the big places like ours so that they could easily be converted into two smaller ones seemed to suggest that they intended to take the lot back at some future date (after all, they'd paid to build them !).
I don't think there could have been any politics involved. It might have been that a desire to get their former big park back outweighed the need for more housing (but that's just my guess).
Danny.
