HMS Petersfield
HMS Petersfield was a Hunt-class [minesweeper (1916)|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.
