Geograph - photograph every grid square

If one looks carefully at the photographs of the Mulberry trials at Garlieston (IWM have them), it certainly looks like the line of barges supporting the Whale roadways to the Spud pierhead includes three FCBS (the zebra fenders in particular). However, these were trials and in the same way that the Hugh Iorys Hughes 'Hippo & Crocodile) was rejected, as was Swiss Roll for carrying trucks, I believe the Beetle pontoons were selected. There is zero photographic evidence that I have seen of the FCBs at Normandy, and that includes the Petrol Barges. Exercise Jantzen in 1943 was disastrous as regards the PB200s taken there - they leaked east quantities of petrol all over the beach near Tenby...This week I found evidence of 60 mothballed FCBS just off the Thames in 1951 and they had disappeared by 1956. My view, the Rainham 16 never left the Thames and were seen as an expedient but surely ineffective stopgap solution during the floods of 1953...Basically, a dumping exercise that morphed into an urban myth of concrete Mulberry Petrol barges towed back from Normandy to help with the floods, a myth perpetuated by plaques and oft repeated 'it is rumoured' statements on the Internet. Mulberry was a harbour concept (originally conceived by Guy Maunsell) and has nothing to do with concrete barges
