Hello all. In the local history book 'Hayle in WW2' there is a description of barges being built from prefabricated components on some reclaimed land in the estuary. The book describes them as 'Rhino Barges' and states that they were assembled by a unit of the US Army under a Captain Marquette. It says that some British labour was also used, provided by Frank Curtis Ltd of Totnes, Devon and that the operation was also using sites in Truro and Fowey. It gives some detail about the delivery of the components to Hayle, saying that they went by rail to either St Erth station or to a siding off the Hayle Wharves branch line relaid on the old alignment which is now King George V Memorial walk. From there they went by flat bed truck to the assembly site, resulting in several accidents. A photo in the same book shows the barges under construction. It's not crystal clear but each barge seems to have four roughly square shaped dark areas on the deck - these may be hatches. Another source is Longshore Soldiers: Army Port Battalions in WWII: History of the 13th Major Port, part 2 . This gives the sites as Totnes, Hayle and Truro, quotes the unit as '13th Major Port' and states that Totnes built wooden barges wih steel ones at Hayle and Truro. The above seems to be a variation on the text in 'The Transportation Corps: Operations Overseas' which is available free on Google books. This says that the vessels were 104 ft knocked down (KD) steel barges and 60ft KD wooden barges. Once again, it states that it was the US Army organising the assembly. I've also found this site US Army Barges which provides a list of the manufacturers of US Army 104 ft KD (and other) barges in the US. Whatever they were, the remains of the Hayle site show up very well on the postwar aerial photos. For example, at the top right of this 1947 image EAW007752 ENGLAND (1947). Imperial Chemical Industries British Ethyl Works at North Quay, Hayle, 1947 | Britain From Above To my understanding, the term 'Rhino Barge' refers to craft constructed from the SeaBees Naval Lighterage (NL) system. The size is not unlike the Hayle photo but the NL system was essentially a raft of roughly cubic boxes and would not allow hatches, nor does the Hayle photo show any evidence of the ramp or propulsion system found on Rhino barges. On balance my belief is that the things assembled at Hayle were the US Army 104ft steel KD barges. Some folks disagree with me on this point. Whether I'm right or not about what was built at Hayle, I've so far been unable to find out much about the 104ft KD barges, such as... In what form were they shipped to Britain? What were they used for once assembled? The location of the Hayle site is clear but where exactly were the other assembly sites? Does anyone know? Does anyone know any more about the operation at Hayle? For example I can see no evidence of rail tracks in situ or having been recently removed from KGV Memorial walk in the 1947 and 1950 aerial photos. Thanks in Advance.
