On October 12 and 13, the Battle of Quatiguá took place (possibly the biggest fight of the revolution), although it has been little studied. Quatiguá is located to the east of Jaguariaíva, near the border between São Paulo state and Paraná.
Margaret's early life was spent primarily at the Yorks' residences at 145 Piccadilly (their townhouse in London) and Royal Lodge in Windsor. The Yorks were perceived by the public as an ideal family: father, mother, and children, but unfounded rumors that Margaret was deaf and mute were not completely dispelled until Margaret's first main public appearance at her uncle Prince George's wedding in 1934.
Armstrong was featured as a guest artist with Lionel Hampton's band at the famed second Cavalcade of Jazz concert held at Wrigley Field in Los Angeles which was produced by Leon Hefflin Sr. on October 12, 1946.
On 12 October Townsend returned from Brussels as Margaret's suitor. The royal family devised a system in which it did not host Townsend, but he and Margaret formally courted each other at dinner parties hosted by friends such as Mark Bonham Carter. A Gallup poll found that 59% of Britons approved of their marrying, with 17% opposed. Women in the East End of London shouted "Go on, Marg, do what you want" at the princess. Although the couple was never seen together in public during this time, the general consensus was that they would marry. Crowds waited outside Clarence House, and a global audience read daily updates and rumors on newspaper front pages.
Margaret may have told Townsend as early as 12 October that governmental and familial opposition to their marriage had not changed; it is possible that neither they nor the Queen fully understood until that year how difficult the 1772 Act made a royal marriage without the monarch's permission.
Thatcher narrowly escaped injury in an IRA assassination attempt at a Brighton hotel early in the morning on 12 October 1984. Five people were killed, including the wife of minister John Wakeham. Thatcher was staying at the hotel to prepare for the Conservative Party conference, which she insisted should open as scheduled the following day.
On 12 October 1999, the Russian forces crossed the Terek and began a two-pronged advance on the capital Grozny to the south. Hoping to avoid the significant casualties that plagued the first Chechen War, the Russians advanced slowly and in force, making extensive use of artillery and air power in an attempt to soften Chechen defenses.
On 12 October 2000, the USS Cole bombing encouraged several members to depart. Mohammed Atef went to escape Kandahar, Zawahiri to Kabul, and Bin Laden fled to Kabul, later joining Atef when he realised no American reprisal attacks were forthcoming.
Encore, released in 2004, was another success. Its sales were partially driven by the first single, "Just Lose It", which contained slurs about Michael Jackson. On October 12, 2004, a week after the release of "Just Lose It", Jackson phoned the Los Angeles-based Steve Harvey radio show to report his displeasure with its video (which parodies Jackson's child molestation trial, plastic surgery and the 1984 incident when Jackson's hair caught fire during the filming of a commercial).
On 12 October 2016 the inaugural meeting of the Legislative Council, two Youngspiration legislators Baggio Leung and Yau Wai-ching took the oaths of office as an opportunity to make pro-independence statements. The two claimed that "As a member of the Legislative Council, I shall pay earnest efforts in keeping guard over the interests of the Hong Kong nation," displayed a "Hong Kong is not China" banner, inserted their own words into the oaths and mispronounced "People's Republic of China" as "people's re-fucking of Chee-na".
