From Flintshire Observer Mining Journal and General Advertiser Thursday 26th May 1887
  TERRIFIC GALE. - LOSS OF A FLAT AND TWO LIVES. Early in the morning of Friday last [20th May 1887], a gale of unusual force sprang up from the north-west, which blew with unabated fury accompanied by blinding showers of hail and rain up to 10 a.m., when it somewhat lulled. About 9 o'clock, information reached Mostyn, that a vessel had sunk higher up the estuary, opposite to Coed Mawr [between Llanerch y Mor and Greenfield], and that the crew were clinging to the rigging. The steam tug Taliesin, with several seamen on board beside her own crew, volunteered their assistance among whom was Captain Dawson, harbour master at Mostyn. They immediately proceeded to the scene of the disaster and found a flat's mast out of water with one man clinging to it. A boat was launched from the steamer and promptly manned by four sailors, viz.:- John Davies and Charles Williams belonging to the Taliesin, and William Lloyd and Samuel Jones of the Mostyn steamer Swiftsure, and, with the assistance of the tug, skilfully managed by Capt. Charles Coppack, the man was reached and rescued from his perilous position. This work was accomplished with much difficulty, as the waves dashed with great force over the mast. The man was benumbed and unconsious from exposure, having been lashed to the mast for three hours. He was kindly treated on board the tug boat, dry clothing and restoratives being supplied him, he was put to bed and in a few hours he was sufficiently recovered to be able to go about.

The captain who was seen by his mate to struggle to save his boy of 14 years of age, was carried away by the waves and disappeared. Both the father and the son were clinging to the mast, and it is supposed that the boy was washed off by a wave, and the brave father plunged into the sea and met his death in the endeavour to save the life of his son. The vessel proved to be the "Glittering Star," (the property of Mr. Thos. Robinson, of Water-street, Liverpool), Capt. Thos. Foster, residing at Birkenhead who has left a wife and several little children. The vessel was engaged at the time lightening the cargo of the (ss) S. W. Kelly, from Spain to Mostyn, lying in Mostyn deeps, which consisted of iron ore for the Darwen and Mostyn Iron Co. The flat had a quantity of iron ore on board, at the time of the disaster. She had dragged her anchors and drifted on to the Salisbury Bank. The bodies of the captain and his son have not yet been recovered.

So violent was the gale and the high sea which was running up the Dee that the schooner Mag of Chester while riding to her anchors at Llanerchymor deeps had both her masts carried away overboard. All the other vesaels in the river rode the gale out in safety and no further casualties to shipping are reported along the coast. Evidently the damage would have been greater but for the proportionately low state of the tides. The violence of the storm was also felt on the land in the neighbourhood, roofs, chimney pots, etc., suffered much and trees were also up-rooted.

From Liverpool Daily Post - Wednesday 25 May 1887
  The extraordinary depth of the "Sands of Dee," which Charles Kingsley has described in his touching song, is now being painfully illustrated by the wreck of the schooner [sic] Glittering Star. She struck the sands during the late gale, and her captain and his son were drowned. Since then she has been gradually settling down. And now she has sunk level with the sands at low water, and at high water she is submerged. In another week she will have disappeared.

Postcript The Glittering Star continues to be listed up to the 1940s, so must have been refloated and repaired. She is not included in the BOT wreck returns, either.

Flat Ellen Bradshaw, wooden, 66 tons, built Northwich 1852, ON 56590, registered Runcorn and then Liverpool
Voyage Connah's Quay to Runcorn with burnt ore.
Sunk on Salisbury Bank 29 September 1884.
BOT wreck return states owned Aston of Queensferry, Captain Wynn plus crewman saved,
MNL gives owner as Jardine, Dublin, in 1884, and not listed 1885.

Although her demise does not seem to be recorded in local papers, previous voyages in 1883 and 1884 (but not 1885) are recorded between Connah's Quay and Liverpool, with Captain Wynne. Also a previous incident involving this vessel is recorded in newspaper Flintshire Observer, Thursday 19 July 1883:
ACCIDENT TO A VESSEL. - While the flat Ellen Bradshaw was going into her berth on Wednesday [18-7-1883] with a cargo of iron ore, which she had been fetching from the ss Eddlethorpe in the Mostyn deep, she sank, but was ultimately righted when the tide had receded.
