The mutiny broke out on 4 April 1807, while Lieutenant-Colonel Barnes was in Valletta.
It involved 200 Greeks and Albanians who killed Lieutenant Schwartz, Captain De Wattville, Gunner John Johnstone and a number of privates.
They also wounded Major Schumelketel and three other officers.
They removed the British flag and replaced it with the Russian ensign, closed the fort's gates and raised the drawbridge.
The mutineers took the regimental officers and their families hostage, and forced about 20 British artillerymen to aim the fort's guns and mortars at Valletta.
The revolt was led by a Greco-Bulgarian named Caro Mitro.

Some men who had escaped from the fort informed the British of the mutiny.
The Royal Maltese Regiment and the 39th (Dorsetshire) Regiment of Foot took positions on the glacis of the fort, while the guns of Fort Saint Elmo and Fort Saint Angelo were trained on Ricasoli.
In a message, the mutineers demanded to be discharged and to be sent home, with money and a pardon from Villettes.
They threatened to open fire on Valletta, but Villettes refused their demands and ordered them to surrender.

On the second day, more guns were trained towards Ricasoli, but no further action was taken since Villettes intended to starve out the mutineers in a siege.
A second message from the rebels demanded food and provisions, again threatening to bombard Valletta, but their demands were again ignored.

On the third day, the mutineers sent one of the hostages, an officer, with a message from the mutineers, which was ignored once again.
The officer told the British authorities of conditions in the fort, but had to return since they had kept his wife.
Shortly afterwards the rebels began fighting among themselves, and a faction which was ready to surrender hoisted the white flag; another faction took it down.
Seeing there was disagreement among the rebels Villettes sent a delegation to negotiate with them, but they still refused to surrender.

On the fifth day, 8 April, the families of the officers held hostage were released since the mutineers were running out of food.
The rebels sent an ultimatum threatening to destroy the fort unless provisions were sent.
When it expired they sent another in which they threatened to kill all the remaining hostages.
Meanwhile, there was more infighting between the rebels, and a group of Germans and Poles managed to open the gates of the fort.
While most of the mutineers escaped and surrendered, some twenty others remained inside behind the re-closed gates.

On 10 April, the remaining mutineers fired on Valletta, though they caused no injury.
Villettes then ordered that the fort be stormed.
A party of 40 men under Lieutenant de Clermont, who was himself part of the Froberg Regiment, scaled the fort and took control of it, taking no losses in the process.
The fort fell but six rebels retreated into the gunpowder magazine, threatening to blow it up.
After two days, they blew up the magazine's 600 barrels of gunpowder, and killed three British sentries.
In the ensuing confusion the six rebels managed to escape to the countryside.
