During 1985, Patrick Kelly became leader of the Provisional IRA East Tyrone Brigade. He, along with East Tyrone Brigade members Jim Lynagh and Pádraig McKearney, advocated using flying columns to destroy isolated British Army and RUC bases and stop them from being repaired. The goal was to create and hold "liberated zones" under IRA control that would be gradually enlarged. Although IRA Chief of Staff Kevin McKenna turned-down the flying column idea, IRA Northern Command approved the plan to destroy bases and prevent their repair. In that year alone there were 44 such attacks. Among the most devastating was the Newry mortar attack in March.
