The escaping liquid dislodged the valve of another vessel and destroyed several large barrels: between 128,000 and 323,000 imperial gallons (580,000–1,470,000 L; 154,000–388,000 US gal) of beer were released in total.
The resulting wave of porter destroyed the back wall of the brewery and swept into an area of slum dwellings known as the St Giles rookery.
[2] In 1809 Sir Henry Meux purchased the Horse Shoe Brewery, at the junction of Tottenham Court Road and Oxford Street.
[4][a] Henry Meux emulated his father's large vat,[4] and constructed a wooden vessel 22 feet (6.7 m) tall and capable of holding 18,000 imperial barrels.
[10][11][12] The rookery, which covered an area of eight acres (3.2 ha), "was a perpetually decaying slum seemingly always on the verge of social and economic collapse", according to Richard Kirkland, the professor of Irish literature.
[19] An hour after the hoop fell off, Crick was standing on a platform thirty feet (9.1 m) from the vat, holding the note to Mr Young, when the vessel, with no indication, burst.
[20] Some of the bricks from the back wall were knocked upwards, and fell onto the roofs of the houses in the nearby Great Russell Street.
[29] Eleanor Cooper, a 14-year-old servant of the publican of the Tavistock Arms in Great Russell Street, died when she was buried under the brewery's collapsed wall while washing pots in the pub's yard.
With insufficient drainage, the beer flowed into cellars, many of which were inhabited, and people were forced to climb on furniture to avoid drowning.
[23] Cornell points out that the popular press of the time did not like the immigrant Irish population that lived in St Giles, so if there had been any misbehaviour, it would have been reported.
[6] The area surrounding the rear of the brewery showed a "scene of desolation [that] presents a most awful and terrific appearance, equal to that which fire or earthquake may be supposed to occasion".
[35] The details of the victims were read out as: Hodgson took the jurors to the scene of the events, and they viewed the brewery and bodies before evidence was taken from witnesses.
