 In May 1797 , whilst under the command of Captain Robert Fancourt , Agamemnon was involved in the Nore mutiny . On 29 May , the North Sea squadron lying in the Yarmouth Roads was ordered to sea . Only three ships , Adamant , Agamemnon and Glatton , obeyed the signal , but Agamemnon 's crew later mutinied , and sailed the ship back to Yarmouth Roads . The ship was then taken to join the main mutiny at the Nore anchorage , along with Ardent , Isis and Leopard , arriving on 7 June . After a blockade of London was formed by the mutineers , several ships began to desert the wider mutiny , in many cases being fired upon by the remaining ships . Order was eventually restored aboard Agamemnon when the loyal seamen and marines forcibly ejected the hard @-@ line mutineers from the ship . Captain Fancourt was able to secure a pardon for the remaining ship 's company .
