HMS Petersfield

HMS "Petersfield" (ex-Portmadoc) was a Hunt-class minesweeper of the "Aberdare" sub-class built for the Royal Navy during World War I. She was not finished in time to participate in the First World War. Re-commissioned at Hong Kong on 23 February 1925 for service on the China Station as an Admiral's yacht. She was wrecked on 11 November 1931 off Tung Yung Island, with the C-in-C China Station Admiral Sir Howard Kelly embarked. Two Courts Martial following her loss resulted in severe reprimands for her Captain, Commander Douglas C. Lang and Navigating Lieutenant, Geoffrey A. H. Pratt, though an imperious meddling throughout the unfolding disaster brought ignominy upon Admiral Kelly, as well.

The "Aberdare" sub-class was armed with a quick-firing (QF) gun forward of the bridge and a QF twelve-pounder (76.2 mm) anti-aircraft gun aft. Some ships were fitted with six- or three-pounder guns in lieu of the twelve-pounder.
Loss.
The minesweeper with the Commander-in-Chief of the China Station, Vice-Admiral Sir William Kelly aboard, ran ashore on the night of Wednesday 11 November 1931 on the north side of Tungyung Island while on a passage from Shanghai to Fuzhou, it was a total loss. The S.S. Derflinger and the Canadian Pacific liner RMS Empress of Asia went to the Petersfield's assistance, and the County-class cruisers Suffolk and Cornwall proceeded rapidly to the scene. The north-east monsoon was understood to have been raging at the time. The Petersfield was a tender to the cruiser Kent, of the Fifth Cruiser Squadron. Admiral Kelly and 73 officers and men on board were rescued, by the Derflinger.
