Three separate watercolour studies on one sheet. The top sketch is of an indeterminate type of destroyer at speed, in port-quarter view, with a small pencil study repeating this slightly broader on the beam in the sky to the right. The lower drawings are a reasonably accurate depictions of the monitor 'M25' in the period 1916-18. She was launched on 24 July 1915 and completed on 5 September, armed with a 9.2-inch gun forward. This was removed soon afterwards for use as a siege gun ashore. In 1916 she was given a 7.5-inch 50-calibre Mark IV gun on an unshielded mount forward, as shown here in the starboard-broadside view to lower right. The two sketches lower left show her on starboard-bow view from ahead, one being very slight and in pencil. In August 1918 the 'M25' was sent to Murmansk as part of Brotish support for the White Russians against the Bolsheviks and had to be blown up on the Dvina River on 16 September 1919, to prevent her fallling into their hands, when she could not get back out to sea because of the shallowness of the water.
