HMS Mandate (1915)

HMS Mandate (1915) was a repeat M class destroyer that served with the Eleventh Flotilla of the Grand Fleet from 1915-17, fighting at Jutland, then with the Northern Division of the Irish Station.

The Mandate was an Admiralty type repeat M class destroyer that was ordered under the First War Programme of September 1914. She was laid down at Fairfield on 29 October 1914, launched on 27 April 1915 and completed on 13 August 1915. When she joined the Grand Fleet she was equipped with mine sweeping gear.

From September 1915-August 1917 she was part of the Eleventh Destroyer Flotilla of the Grand Fleet.

On 11 October the Mandate was at sea with the Grand Fleet when all of the destroyers were ordered back to Scapa Flow because of bad weather. The Mandate was damaged by the heavy seas on her way back to Scapa.

1916

In January 1916 she was one of fifteen repeat M class destroyers that formed the Eleventh Flotilla at Cromarty, along with the flotilla leader Kempenfelt and the light cruiser Castor.

On the eve of Jutland the Mandate was one of twelve Repeat M class destroyers from the Eleventh Destroyer Flotila which were at Invergordon (a smaller part of the flotilla was at Scapa Flow).  She sailed with the fleet on 30 May.

The part of the flotilla at Scapa put to sea with Admiral Jellicoe and the main body of the Grand Fleet by 10.30pm on 30 May. The part of the flotilla at Cromarty was also soon at sea, and joined the main body of the fleet at 2pm on 31 May.

The two main fleets finally came together at about 6.30pm on 31 May. By this point the battleships of the German High Seas Fleet were heading north, while the battleships of the Grand Fleet were forming a line running roughly east to west in front of them. For a few minutes the British were able to concentrate their fire on the leading ships of the German line, but the Germans then carried out their famous sixteen point turn, and within a few minutes were heading away south into the North Sea mist. However Admiral Scheer then mis-judged the British movements, and turned back east in the hope that he could pass behind the main British force. Just after 7pm the Germans found themselves steaming straight towards Jelicoe’s battleships, and by 7.15 the bulk of the Grand Fleet was finally able to open fire on the Germans. Once again Scheer was forced to reverse course. During this phase of the battle the destroyer flotillas struggled to keep up with the fast moving battleships and rather disappear from the narrative.

Jellicoe now couldn’t be sure which way the Germans had gone and struggled to make firm contact with Scheer during the night. However the fighting didn’t end. Part of the 11th flotilla was now on the port side of Jellicoe’s flagship, with the flotilla cruiser Castor. They spotted smoke to the W.N.W. and discovered twelve German destroyers apparently preparing to attack Beatty’s battlecruisers. The 11th Flotilla and the 4th Light Cruiser Squadron forced the German destroyers away, and the Grand Fleet made contact with the Germans for the third time. Once again the Germans turned away under heavy fire, and by 8.35pm had disappeared into the mist once again. 

Jellicoe was unwilling to risk a night battle, and at 9.17 ordered the fleet into its night cruising formation. The battleships formed up into lines in their divisions, with the destroyers following behind. The entire formation began to move south in an attempt to keep between the Germans and their home bases. By 10pm the destroyer flotillas were in line, with the 12th Flotilla at the eastern (left) end of the line, then the combined 9th and 10th Flotillas, 13th Flotilla, 4th Flotilla and finally the 11th Flotilla at the western (right) end of the line.

The fighting had ended with the Germans sailing south, just to the west of the Grand Fleet. Admiral Scheer’s plan was to try and turn east and cut behind the Grand Fleet, to reach Horn Reefs and a safe route home. His leading cruisers were sent ahead to try and find the British, and soon after 9.30 then ran into the 11th Flotilla, which was now at the back-right corner of the Grand Fleet. They weren’t at all sure who was approaching them, and so while some of the flotilla fired torpedoes, most of the destroyers believed these were British ships.

1917

In January 1917 Commodore Tyrwhitt at Harwich was ordered to send eight of his destroyer to Dunkirk to help protect against any German raids. To replace them the Grenville and eight destroyers from the Grand Fleet (Morning Star, Moon, Musketeer, Mandate, Opal, Nonsuch, Napier and Strongbow) were sent to Harwich arriving on 19 January. They almost immediately took part in a large minesweeping operation on the Swarte Bank (to the north-east of Lowestoft). After this operation Tyrwhitt was told he could keep the destroyers for the time being.

On 13 January 1917 one of her motor boats was lost while she was at sea.

On 8 March 1917 the Mandate collided with HM Trawler Euripides in Gutter Sound at Scapa Flow.

From September 1917 to December 1918 the Mandate served with the Second Destroyer Flotilla, part of the Northern Division of the Coast of Ireland Station, based at Buncrana.

On 13 December the Mandate and Anchusa collided off Buncrana.

1918

In January 1918 she was undergoing repairs at Belfast.

Post War

The Mandate was awarded a battle honour for Jutland.

In November 1919 she was in the hands of a care and maintenance party in the Devonport reserve.
