He also mentioned that the two other men - Ryan Ali and Ryan Hale, who are standing trial also accused of affray along with Stokes - left the club and accompanied O'Connor and Barry.
Jurors have been shown footage of Stokes brawling with Ali and Hale, who are friends, in the early hours of September 25 past year after walking away from the Bristol nightclub Mbargo.
Further CCTV footage showed Stokes approaching a retreating Ali, Adams said, adding: "From this point it is very hard to identify who is involved".
The jury was also shown CCTV footage that, it was alleged by the prosecution, shows Hale running back towards the main group with a length of metal.
Cunningham claims Stokes started mimicking the voices and gestures of two gay nightclub patrons, Kai Barry and William O'Connor, in a derogatory manner. "Mr Barry grabs Mr Ali around the groin area". Mr Barry appears to link arms with Mr Ali and is shrugged off and pushed away.
Mr Hale collapsed to the floor outside a shop window before picking himself up after 20 seconds, disappearing from view and then returning.
"It was homophobic in nature". Stokes said "matters had become too serious to ignore and that I had to intervene".

PC Stacey Alway, who arrested Stokes, told the court: "From the moment I approached him (Stokes) he calmed down and was compliant".

- "I was worried": Stokes -In a later statement, Stokes told officers: "These men were speaking to the gay guys in what I would call a harsh and abusive way". I struck Ryan Ali with my right hand just after he had delivered the blow on Kai and as he came at me with the bottle and had it raised.
"I believe I felt threatened", he said.
He told police he "did not feel in any way drunk or impaired" and that he had consumed two or three pints at dinner before a further five drinks of vodka with a mixer in the Mbargo nightclub.
"I didn't feel I had an option. I was concerned for myself and others", he claimed.
