Until about midday the Pool of London was an astonishing scene. Steamboats and shipping of all sorts lay there, tempted by the enormous sums of money offered by fugitives, and it is said that many who swam out to these vessels were thrust off with boathooks and drowned. About one o'clock in the afternoon the thinning remnant of a cloud of the black vapour appeared between the arches of Blackfriars Bridge. At that the Pool became a scene of mad confusion, fighting, and collision, and for some time a multitude of boats and barges jammed in the northern arch of the Tower Bridge, and the sailors and lightermen had to fight savagely against the people who swarmed upon them from the riverfront. People were actually clambering down the piers of the bridge from above.
