A Catterick Garrison soldier is accused of trying to stab a roommate in the head
Private James Farrell, 18, said he plunged a knife into the bed of Rifleman Curtis Horbury so hard that it went through the mattress, into the bed frame and sent a shockwave back into his arm.
Farrell said he had been bullied by his roommates at Catterick Garrison in North Yorkshire and that Rifleman Horbury was the "ringleader".
Commander Douglas Ward, prosecuting, said the knife was aimed at the head and neck region of Rifleman Horbury, who was lying in bed texting, and he had to roll out of the way to avoid the blow.

Just to scare him, get him to leave me alone
Private James Farrell
He told today's hearing at Colchester Garrison in Essex that he started his training at Catterick Garrison in September 2016 and was bullied "nearly the whole time" he was there.
He said he was verbally abused, physically struck "a few times" and that his roommates would throw rubbish including half-empty Coke cans into his bed space.
On the day of the incident, other trainee soldiers were "ripping into him" for wearing the wrong uniform on Remembrance Sunday and they asked questions about his home background after he said he did not get the grades to become an Army medic, the court heard.
