12 April 1831

Soldiers marching on the Broughton Suspension Bridge in Manchester, England result in it collapsing.

On 12 April 1831, the 60th Rifle Corps carried out an exercise on Kirsal Moor under the command of Lieutenant Percy Slingsby Fitzgerald, the son of John Fitzgerald, Member of Parliament and brother of the poet Edward FitzGerald. As a detachment of 74 men returned to barracks in Salford by way of the bridge, the soldiers, who were marching four abreast, felt it begin to vibrate in time with their footsteps. Finding the vibration a pleasant sensation some of them started to whistle a marching tune, and to “humour it by the manner in which they stepped”, causing the bridge to vibrate even more. The head of the column had almost reached the Pendleton side when they heard “a sound resembling an irregular discharge of firearms”. Immediately, one of the iron columns supporting the suspension chains on the Broughton side of the river fell towards the bridge, carrying with it a large stone from the pier to which it had been bolted. The corner of the bridge, no longer supported, then fell 16 or 18 feet into the river, throwing about 40 of the soldiers into the water or against the chains. As the river was low and the water only about two feet deep at that point none of the men were killed, but 20 were injured, including six who suffered severe injuries including broken arms and legs, severe bruising, and contusions to the head.

An investigation found that a bolt in one of the stay-chains had snapped at the point where it was attached to the masonry of the ground anchor. There was criticism of the construction method used, as the attachment to the ground anchor relied on one bolt rather than two, and the bolt was found to have been badly forged. A number of other bolts were also bent but had not broken. It emerged that three years previously the distinguished Engineer, Eaton Hodgkinson FRS, had expressed some doubt about the strength of the stay chains compared with that of the suspension chains. He had said that they should be rigorously tested, but they were not. It also came to light that some time before the accident one of the cross bolts had started to bend and crack, although it was believed to have been replaced by the time of the accident. The conclusion was that, although the vibration caused by the marching had precipitated the bolt’s failure, it would have happened anyway.

The History of The University of Alabama begins with an act of United States Congress in 1818 authorizing the newly formed Alabama Territory to set aside a township for the establishment of a “seminary of learning.” Alabama was admitted to the Union on March 20, 1819 and a second township added to the land grant. The seminary was established by the General Assembly on December 18, 1820 and named The University of the State of Alabama. The legislature appointed a Board of Trustees to handle the building and opening of the campus, and its operation once complete. The Board selected Tuscaloosa, then capital of the Alabama, as the site of the university in 1827, and opened its doors to students on April 18, 1831.

Offering more than 100 undergraduate degree programs, students can also create their own major and minors. The university is home to four different museums including the Alabama Museum of Natural History, which has the Hodges meteorite on display; students are granted free admission. Additionally, students who are interested in the arts can participate in Creative Campus, a student-centered arts advocacy organization with over 40 interns. Seven UA students won Fulbright awards for 2016–17, and five won awards to research and teach abroad. One third of students participate in the 62 social Greek organizations on UA’s campus. The Alabama Crimson Tide compete in Division I athletics and has one of the strongest football teams in the U.S., having won 25 SEC titles and 16 national championships. The school’s rivalry with Auburn University is one of the staunchest in the nation.
