Question: Was Tweed ever convicted after it became known that he was corrupt? Passage 1:He served aboard the submarines HMS Porpoise and HMS Thrasher earning the Distinguished Service Cross for his service in the latter in 1942. As commanding officer of the submarine HMS Sceptre he sank almost 15,000 tons of enemy shipping and took part in Operation Source, the attacks on heavy German warships in Norwegian waters by towed midget submarines. He commanded the submarine HMS Alderney from 1946, the submarine HMS Aeneas from 1950 and then the aircraft carrier in the 1960s. He became Director-General Weapons (Naval) at the Ministry of Defence in 1969 and Deputy Chief of the Defence Staff (Operational Requirements) in 1970 before retiring in 1973.
Passage 2:The caucus of Democratic State legislators met on January 15, State Senator Albert P. Laning, of Buffalo, presided. All but one of the legislators were present, only Assemblyman John M. Roscoe, of Schoharie County, was sick. The caucus nominated Francis Kernan for the U.S. Senate. Kernan had been the Democratic/Liberal Republican candidate for Governor in November 1872 but had been defeated by John Adams Dix. Now Kernan was the choice of Tammany boss John Kelly who had succeeded the corrupt William M. Tweed. Kelly was opposed by John C. Jacobs, who proposed Ex-State Senator Henry C. Murphy, Jacobs's predecessor from the 3rd District, and the Democratic candidate who had lost the U.S. Senate elections in 1867 and 1869 when the Democrats were the minority. Kelly stood firm in his intention to dominate the Democratic Party, and had the caucus nomination made by viva voce vote instead of the more traditional secret ballot. Jacobs and Murphy had expected to get votes from many legislators who would not dare to cross Kelly openly, but had to abandon their hopes when the secret ballot was voted down 74 to 13.
Passage 3:In early September 1914, 18-year old Lewis attended a recruitment meeting organised by a Major Birt, who was also his father's employer, which drew crowds of 20003000 people before enlisting in the 11th (Service) Battalion of the Welsh Regiment which had been formed little over a month before as the Cardiff Commercial Battalion, a pals unit. At 10a.m. the next day, Lewis, was one of 75 local volunteers who left Milford Haven before being split into smaller groups with Lewis and 45 others travelling to Maindy Barracks in Cardiff, the rest joining the Royal Engineers or the Royal Artillery. Two days later, his unit was moved to Lewes as part of the 67th Brigade. He also underwent training at Eastbourne, Hastings, Aldershot and Seaford. On 5 September 1915, just over a year after enlisting, Lewis and his unit sailed to Boulogne, France from Southampton. Several days after his arrival, he was attached to the 9th Border Regiment as a machine gunner.
