After several hours of stalemate when the RUC stopped the parade from marching through a Catholic area of Portadown, several hundred more Protestants joined the demonstrations. In response the RUC drafted in extra riot police as tension grew after all entrances were blocked off by the RUC to prevent the march. Hundreds of police officers used Land Rovers to close off the routes while Republicans blocked the Garvaghy Road along which the Orangemen traditionally parade after the annual service at Drumcree Parish Church, just outside the County Armagh town. The 800 Orangemen remained outside the church hoping they might be allowed to march. It was the first time the parade had been blocked off in .200 years.
