A schoolboy who suffered brain injury in a hammer attack at a Wiltshire school has told a court he still suffers from short-term memory loss.
Henry Webster suffered brain injury in the attack at the school
Henry Webster, 16, was punched, kicked and hit repeatedly on the head at Ridgeway School in Wroughton.
Four teenagers, Wasif Khan, 18, Amjad Qazi, 19, and two boys aged 15 and 16, were charged with inflicting GBH.
At Bristol Crown Court, Henry told the jury how he struggles to remember since the attack in January 2007.
"Someone can tell me something and I can forget it," he said. The teenager also testified that the first hammer blow was so hard it caused him to see stars and blurred his vision.
The hammer has never been found.
The court has been told Henry suffered three skull fractures, in violent scenes which the court was told resembled "a Quentin Tarantino film".
A 16-year-old witness later described the moment one of the group pulled a claw hammer out of their sleeve before attacking their victim.
Henry's head was struck with such force that a hammer indent was left on his skull with paramedics describing his injuries as life-threatening.
The boy, who cannot be named, said: "One guy pulled the hammer out of his sleeve and just smacked him.
"As soon as he hit Henry, he fell to the ground. As he lay there bleeding, people kept kicking him."
The court had previously heard how Mr Webster had agreed to a one-on-one fight with another schoolboy after "barging" into a group of Asian boys.
The case continues.
