An armistice with Turkey was signed on board HMS Agamemnon at Fort Mudros, Lemnos, in the captain's after cabin at 8.45 pm Greenwich time 30th october 1918, effective the 31st, 1 month after that signed with Bulgaria and just prior to that with the Austro Hungarian empire, leaving only the armistice with Germany amongst the Central Powers to conclude hostilities when on 11th november leaving Humber and assorted British warships in the Gulf of IIzmid/t enforcing the Ottoman deal. The demise of each empire would have repurcussions still felt to this day, additionally Russia was divided, the whites needing outside support. Humber remained behind while Mersey and Severn briefly ventured up the Danube before withdrawal and then the trio were towed back to Britain when only Humber was to see further service in 1919 with a tow to north Russia and extensive operations against the reds along the Dvina river with other RN shallow draft gunboats but not shallow enough as the river levels dropped so low she had to land all her guns bar the forward twin 6" which she still mounted. A messy affair which saw all RN warships withdrawn, at least those that were'nt sunk or expended. 1919 was a costly year with the attendant pandemic claiming as many lives the Great War had. This Russian escapade is the reason you may see some dates for the conflict 1914-1919, not 1918.
What can you do with a shallow draft gunboat surplus to requirements, why not convert her into this...
which the Dutch shipbreaker Frank Rijsdijk thought was a grand plan with huge benefits. Firstly she was well maintained, low mileage, well at least using her own machinery which in turn meant she was self propelled, had loads of deck space for landing broken and twisted metal and once the entire 6" gun, magazine/shell rooms were removed a huge capstan was installed whilst the conning tower was a perfect control position and she still floated in shallow water. When and where all this was accomplished is obscure but old Frank knew the ropes, additionally having his thumb in many dykes and British breaking outfits especially Upnor, once he'd fitted a 90 ton crane this well known photo of Humber, where he considerately retained her name, was taken during the salvage of destroyed battleship Bulwark in the Medway july 1935. Her post WW2 history is obscure.
Humber was not the only warship with a crane conversion, here is the US craneship 1, ex battleship Kearsarge BB5...
https://navalhistoria.com/crane-ship-no-1/We have met four ships named for rivers in recent weeks. Mersey, Severn,Trent, Danube and. No.
There is no river Humber, it is solely an estuary.
Thats all folks. Sean.
