Seven teenagers have been convicted of brutally battering a schoolboy close to death with a claw hammer.
Mr Webster suffered brain injury in the attack
Henry Webster, 16, from Wiltshire, was left fighting for his life after being hit in scenes the prosecution compared to a "Quentin Tarantino film".
Four teenagers - Wasif Khan, 18, Amjad Qazi, 19, and two boys aged 15 and 16, were found guilty of the attack.
Nazrul Amin, 19, and two teenagers had previously admitted inflicting grievous bodily harm.
The convictions, delivered at Bristol Crown Court on 14 February, can be made public after Judge Carol Hagen agreed to lift reporting restrictions she had implemented when the jury returned its verdict.
Henry Webster, who attended Ridgeway School in Wroughton, Wiltshire, suffered three skull fractures during the violence.
One caused a brain injury and required surgery to save his life.
Describing the day of the attack in January last year, James Patrick, prosecuting, said a fight was arranged after Henry had "barged" into a group of boys in a school corridor
Mr Patrick added: "It was to be a fair fight. A one on one - or so Henry thought. But he had not reckoned on the fact it was not to be one on one."
The jury had been told how a gang of males from Swindon travelled to Wroughton for the fight, which had been co-ordinated through a sequence of phone calls and text messages.
"As he (Henry) came into the playground he was attacked by a group.
"He was knocked to the ground, he was kicked, punched and repeatedly hit over the head with a hammer."
In a video interview filmed six days after the attack, Henry told police the group had ambushed him.
He said: "I heard screams, then I was punched in the back of my head. I was curled up on the floor but they repeatedly kept hitting me.
"Then I felt the hammer hit the back of my head. I know it was a hammer because if it was a punch, your vision does not change.
"As I got hit, my vision turned to stars - it all separated, what I could see, because it was so powerful."
The seven youths will be sentenced at a later date.
