Several prison vans also arrived at the jail, which is surrounded by acres of countryside.
Beyond the 30ft (9m) curtain walls, shouts from inmates could be heard above the barking of prison guard dogs.
The incident was resolved in the early hours of Thursday, and no-one was injured.
A Prison Service spokeswoman said: "Specially trained prison staff successfully resolved an incident at HMP Long Lartin on 12 October. There were no injuries to staff or prisoners.
"We do not tolerate violence in our prisons, and are clear that those responsible will be referred to the police and could spend longer behind bars."
Long Lartin has housed a number of high-profile prisoners, including radical Muslim cleric Abu Hamza and murderer Christopher Halliwell.
