MB436 was commissioned by the Admiralty to J. W. Brooke & Co, Ltd., Oulton Broad, Norfolk . The order was placed on 27 January 1915 under Admiralty order CP75332/14 which covered a number of similar craft:
Admiralty order CP75332/14
MB435 completed 7 June 1915 went to Belfast to HMS Sir Thomas Picton. In 1919 moved to HMS Triad. In 1934 she was in Shoreham. Later condemned in Bombay in 1935.
MB437 completed 8 August 1915 to HMS Davenport. In 1917 to Calliope to serve as ‘Commodore’s Barge. Condemned Rosyth dockyard 1919.
MB438 completed October 1915 to HMS Cambrian. In 1937 transferred to HMS Colombo. 19 to HMS Enterprise. Broken up in 1946
MB450 completed 5 November 1915 to HMS Intrepid. Transferred to HMS Ceres in 1919. Lost at Sea in 1942 (Maybe in Action)
At Brooke & Co the Build reference was number 80, and was boat number 436, hence MB436
MB436 was despatched on 10 August 1915 to
HMS Calliope to serve as a fast motor launch. Later
the same year she was transferred over to
HMS Royalist when Capt. Mead transferred
command from Calliope to Royalist in August 2015
HMS Royalist was an Arethusa class light cruiser
that fought at the battle of Jutland. In March 1915
she joined the 4th Light Cruiser Squadron of the
Grand Fleet. It was in that role that she took part
in the battle of Jutland, forming part of the screen
that protected the battle squadrons as they
steamed south towards the battle. She then took
part in the destroyer fight at 7.15-7.30 pm (31 May),
as her squadron was the only Light Cruiser
Squadron to have kept in her battle position.
Later on she launched a torpedo at German capital ships, identified as either the pre-dreadnaught battleships or the battlecruisers.
In August 1916 Admiral Jellicoe was absent from the Grand Fleet, recovering from an illness in southern Scotland. The Royalist was the cruiser chosen to wait for him at Dundee, in case the German fleet came out. On 18 August the Germans did indeed make a sortie, and the Grand Fleet put to sea without Jellicoe. He made his way to the Royalist, and was taken to the Iron Duke, to take over command of the fleet. On transferring over from the Royalist to Iron Duke we believe Jellicoe may have used MB436, however its pretty difficult to prove!
In February 1917 HMS Royalist converted to carry 74 mines and joined the 1st Light Cruiser Squadron. She was the most prolific minelayer of her class, laying 1,183 mines in 16 trips. Late in the war HMS Royalist was significantly modified, gaining twin 3in anti-aircraft guns, a kite balloon and having her two rear 4in guns replaced with one 6in gun.
HMS Royalist spent four months in the Baltic (January-April 1919), then spend the rest of the year with the 2nd Light Cruiser Squadron at Harwich. In January 1920 she joined the Portsmouth Reserve.
