The incident came to light in an online blog on Prison UK.
Author Alex Cavendish, a former prisoner, said he was passed the information via "reliable, professional sources inside the system".
"A mass brawl broke out yesterday morning... Prisoners were attacking each other with weapons - and staff," the informant said.
He described the incident as "horrific".
"Staff were trying to save their lives and got battered. Some were seriously injured. Another officer was on the landing unconscious.
"We had ambulances and fire service in, trying to help alongside our healthcare department.
"The wing has been brewing for a while," he added.
A Prison Service Spokesman confirmed that "an incident involving a number of prisoners took place on Friday 21 July".
"We do not tolerate violence against our hard-working staff. Where incidents like this occur, we will always work closely with the police to push for the strongest possible punishment," he added.
The incident is being jointly investigated by the Prison Service and Thames Valley Police.
