UB-128 was surrendered to the Allies at Harwich on 3 February 1919 in accordance with the requirements of the Armistice with Germany. After passing into British hands, UB-128 was towed to Falmouth along with five other U-boats [Note 2] for use in a series of explosive test trials by the Royal Navy in Falmouth Bay, in order to find weaknesses in their design. Following her use on 1 February 1921, UB-128 was dumped on Castle Beach and sold to R. Roskelly & Rodgers on 19 April 1921 for scrap (for £120), and partially salvaged over the following decades, although parts remain in situ.[5]
