The magistrates prohibited the meeting.

It was only postponed for a week, when the people assembled in such formidable numbers (no estimate reckoned them at fewer than 60,000), that the ordinary civil authorities deemed themselves unequal to dealing with it, and called in the aid first of the Yeomanry and then of a hussar regiment.

The soldiers behaved with great forbearance, as soldiers always do behave on such occasions; but they were bound to execute the orders which were given them to arrest some of the leaders, and, in the tumult which was the inevitable consequence of their attempt to force a way through so dense a crowd, three or four lives were, unfortunately, lost.
So unusual a catastrophe called out the energies of both parties.

The Radical leaders published manifestoes declaring the people had been "massacred" by the soldiers by the orders of the government.

Meetings were held to denounce the conduct of the ministers, one being even promoted by Lord Fitzwilliam, as Lord-lieutenant of Yorkshire, a dignity of which he was instantly deprived; while, on the other hand, the grand-juries of Cheshire and Lancashire made reports of the condition of those counties to the Secretary of State, which showed that a most alarming spirit prevailed over the greater part of the district.
