On December 21, 1978, three British soldiers are shot dead when the Provisional Irish Republican Army‘s South Armagh Brigade ambushes an eight-man British Army foot patrol in Crossmaglen, County Armagh, Northern Ireland.

Since the Troubles began, the South Armagh area—especially around Crossmaglen and other similar republican strongholds—is one of the most dangerous places for the British security forces, and the IRA’s South Armagh brigade carries out numerous ambushes on the British Army and Royal Ulster Constabulary (RUC). This includes the 1975 Drummuckavall ambush and the 1978 downing of a British Army Gazelle helicopter which leads to the death of one British soldier and four others being seriously injured.

A number of British security force members are killed in Crossmaglen during 1978. On March 4, British soldier Nicholas Smith (20), 7 Platoon, B Company, 2nd Royal Green Jackets, is killed by an IRA booby trap bomb while attempting to remove an Irish flag from a telegraph pole in Crossmaglen. On June 17, William Turbitt (42) and Hugh McConnell (32), both Protestant RUC officers, are shot by the IRA while on mobile patrol near Crossmaglen. McConnell is killed at the scene, but Turbitt is kidnapped. The next day, a Catholic priest, Fr. Hugh Murphy, is kidnapped in retaliation but later released after appeals from Protestant clergy. The body of Turbitt is found on July 10, 1978.

On December 21, 1978, when the patrol is near Rio’s Bar coming around a bend, a red Royal Mail-type van is spotted by the patrols commander Sergeant Richard Garmory. The van is fitted with armor plating and is facing away from the patrol. Garmory believes the van is in a suspicious place on the other side of the street. He notes what appear to be boxes in the back of the van, which actually provide cover for the IRA Volunteers. IRA members open fire from the back of the van with an M60 machine gun which is fitted down onto the floor in the back of the van. Three other IRA volunteers armed with AR-15-style rifles and another Volunteer with an AK-47 open up on the patrol. The British soldiers on patrol return fire but do not claim any hits. A handful of Christmas shoppers scramble for cover. Three soldiers at the front of the patrol are fatally wounded. They are treated by staff at a nearby health center and then taken to Musgrave Park Hospital but are declared dead on arrival. The soldiers killed are Graham Duggan (22), Kevin Johnson (20) and Glen Ling (18). All are members of the British Armies Grenadier Guards regiment. The patrol commander, Richard Garmory, says of the ambush:

On coming round the bend near the Rio Bar, I saw 40 yards away what looked like a British Rail parcel delivery van parked partly on the pavement on the left facing away from us. It had an 18-inch tailboard with a roll shutter that could be pulled down. The van immediately struck me as highly suspicious because I saw what looked like cardboard boxes piled to the top in the back, all flush with the tailboard so they would fall out if the van moved off fast. I instantaneously put my magnifying sight to my to my eye and saw four firing slits, two above the other two, among the boxes. I immediately opened fire.

Four months later the South Armagh brigade strikes again at British security forces, this time near Bessbrook which is several miles from Crossmaglen. Four RUC officers are killed in the 1979 Bessbrook bombing, when a 1,000 lb. land mine is detonated when the RUC patrol is passing by the bomb, killing all the officers outright.
