The Bishopsgate mutiny occurred in April 1649 when soldiers of Colonel Edward Whalley's regiment of the New Model Army refused to obey orders and leave London.
[1] At the end of the mutiny one soldier, a supporter of the Levellers, Robert Lockyer, was executed by firing squad.
In March eight Leveller troopers went to the Commander-in-Chief of the New Model Army, Lord Thomas Fairfax, and demanded the restoration of the right to petition.
300 infantrymen of Colonel John Hewson's regiment, who declared that they would not serve in Ireland until the Leveller programme had been realised, were cashiered without arrears of pay, which was the threat that had been used to quell the Corkbush Field mutiny.
Five were pardoned but Robert Lockyer, a former Agitator within the regiment, was executed by firing squad in front of St Paul's Cathedral on April 27, 1649.
