At 10p.m. on Friday 3 July, four hours after the violence began, Freeland ordered that the area be put under an indefinite curfew and that anyone on the streets be arrested. British soldiers announced the curfew through loudspeakers on the ground and from helicopters flying low over the streets. The boundaries of the official curfew zone were the Falls Road in the west and north, Albert Street and Cullingtree Road in the east, and Grosvenor Road in the south. However, during the curfew the zone was extended in the southwest as far as Dunmore Street. There were about 3,000 homes inside the curfew zone. After the curfew was announced, up to 3,000 soldiers began moving into the curfew zone supported by armoured vehicles and helicopters. They also began sealing off the curfew zone with barbed wire.
