Radislav Krstic has won more than £50,000 from the British government for failing to protect him from a savage prison attack.
Krstic, who is serving 35 years after being convicted by the International Criminal Tribunal for the former Yugoslavia for his part in the Srebrenica massacre, was being held at Wakefield prison when he was slashed with a razor blade.
Three Muslim extremists stormed his cell at the high security prison and cut his throat before leaving him for dead in the 2010 assault.
They held Krstic down and used a razor blade embedded in a tooth brush handle to cut his throat, neck and face.
Krstic claimed he has been left physically and mentally scarred and accused the prison authorities of negligently failing to protect him from the threat of attack by prisoners.
A judge, sitting at Central London County Court, has now ruled that the Ministry of Justice was negligent and awarded him £52,500 damages.
At the time of the attack, Krstic was being held in Britain under an agreement with NATO.
His attackers were all later convicted of causing grievous bodily harm with intent.
In his ruling, the judge said that Wakefield Prison had no appropriate facilities for protective confinement and Krstic should never have been transferred there.
Radislav Krstic serves now his sentence in a Polish jail.
