The Drummuckavall ambush, an attack by the South Armagh Brigade of the Provisional Irish Republican Army (IRA) on a British Army observation post in Drummuckavall, southeast of Crossmaglen, County Armagh, takes place on November 22, 1975. The attack, which occurs along the border with the Republic of Ireland, results in the deaths of three British soldiers and underlines the inefficiency of conventional military skills to deal with the situation in South Armagh, prompting the deployment of the Special Air Service (SAS) in this area.
During the mid-1970s, the most violent decade of the Troubles in Northern Ireland, the monitoring of the border between south County Armagh and the Republic of Ireland by the British Army is carried out from several static observation posts. The main goal of these observation posts is to prevent attacks launched from beyond the border. These part-time manned positions are highly vulnerable to attack, as proved by a 1974 bomb attack which claims the lives of two Royal Marines at the outpost of Drummuckavall, a townland 3 kilometers southeast of Crossmaglen close to the border.
It is not until 1986, when the first surveillance watchtowers are erected in operations Condor and Magistrate that the British Army tries to regain the initiative in the region from the IRA.
The intelligence and control over the area relies until then, and for a lapse of ten years, mostly on mobile posts comprising small, uncovered infantry sections.
A section of four soldiers from the Royal Regiment of Fusiliers, coming from Crossmaglen, mount an observation post at 2:00 a.m. on November 21, 1975. The observation post is on a slope at Drummuckavall behind bushes overlooking a small stream that runs along the border. Unknown to them, locals had spotted their position and informed the IRA. At 4:20 p.m. the next day, an IRA unit of up to twelve members attacks the observation post. Heavy gunfire kills three of the Fusiliers and disables their communications equipment. A later inquest finds that the IRA unit had fired from two positions inside the Republic. Those killed are James Duncan (19), Peter McDonald (19), and Michael Sampson (20). The only fusilier on guard duty is McDonald, who is manning a light machine gun. The other soldiers are resting or taking a meal. The lance corporal in charge of the party, Paul Johnson, survives the first burst unscathed. He remains flat on the ground but is seriously injured on the wrist, side and back by a second burst of automatic fire after the IRA unit calls on him to surrender. A second call to surrender is made, followed by more gunfire. The IRA unit then withdraws across the border. According to Johnson, they were shouting “Up the ‘RA!” and laughing. Johnson manages to slip away by crawling 25 yards toward a nearby road, where British troops eventually airlift him to safety in a helicopter.
One of the AR-15 rifles used in the attack is found to have been used by the South Armagh Republican Action Force in an attack on the Tullyvallen Orange Hall on September 1, 1975, that killed five civilians.
Shortly after the attack, Merlyn Rees, Secretary of State for Northern Ireland, issues a famous statement dubbing South Armagh Bandit Country. The next year, the British Government declares it is deploying the Special Air Service (SAS) in Northern Ireland, although they had already been deployed unofficially for a number of years. The secretive and undercover nature of this elite force means they are considered the best choice to infiltrate the South Armagh area, after the official report on the action exposes several flaws in the layout of the observation post.
As a complement to the SAS operations, the British Army also changes tactics. Major General Richard Trant establishes small teams of troops, called COPs (Close Observation Platoons), to gather information, often in plain clothes or camouflaged in the landscape. They are also able to set up ambushes, like the ill-fated Operation Conservation on May 6, 1990.
