| We 29 December 1841 | PORTSMOUTH, Tuesday. The Thalia, 42, Captain C. Hope, arrived at Spithead yesterday from the eastward. She has recently come from Leith, where she has been very successful in procuring volunteers to join her. The Powerful, 84, Captain M. Seymour, will come into the harbour this day, and will be paid off as soon as she is unrigged. She was to have come in yesterday, but was prevented by the thick fog which was prevailing at the time the tide would admit of her entering the harbour. Vice-Admiral Sir J.A. Ommanney has struck his flag. The Numa transport, with the detachments of the Royal Artillery and 59th Regiment on board, bound to the West Indies, is still at Spithead, but will sail to-day if the wind is in any way favourable. The detachment of the Royal Artillery has already been upwards of a month on board of her. The Queen, 110, Captain Rich, bent her sails yesterday, and is now all ataunt. She will proceed on Wednesday or Thursday to Spithead. The whole of the ships now fitting out here for foreign service, consisting of the Warspite, 50, Vindictive, 50, Rapid, 10, and Queen, 110, will go out of harbour this week. Ships at Spithead:— Powerful, 84, Thalia, 42, Hazard, 18, Snake, 16, and Numa transport. Ships in harbour.— St. Vincent, Victory, Queen, Warspite, Vindictive, Rapid, Royal George yacht, Excellent and Adventure naval transport. | ||
