Kilfedder leaves the UUP in 1977 in opposition to the party’s policies tending to integrationism, preferring to advocate the restoration of the Stormont administration. For a time he sits as an “Independent Ulster Unionist.” He contests the 1979 European Parliament election under that label, finishing fourth in the count for the three seats, having overtaken the UUP leader Harry West on transfers.
On March 20, 1995, while traveling by train into London from Gatwick Airport, Kilfedder dies of a heart attack. This is the same day that the Belfast Telegraph carries a front-page story saying that an Ulster MP has been targeted as one of twenty MPs invited by the LGBT rights organisation OutRage! in a letter to come out. He dies unmarried and is survived by two sisters.
In October 1964, during the general election campaign, a photo of McMillen is placed in the window of the election office in Divis Street flanked on one side by the Starry Plough flag and on the other by the tricolour. His campaign draws national attention after Ian Paisley demands that police remove the tricolour from McMillen’s election offices. The RUC raids the premises and confiscates the flag, sparking several days of rioting during which McMillen leads several thousand protesters in defiantly displaying the tricolour. He recalls the IRA gaining a “couple of dozen recruits” following the election, but he finishes at the bottom of the poll with 3,256 votes (6%). Around this time, he succeeds Billy McKee as the Officer commanding (OC) of the Belfast Brigade.
McMillen is keen to work for the unity of Protestant and Catholic workers. Roy Garland recalls that McMillan’s grandfather was master of an Orange lodge in Edinburgh and McMillan knew of that heritage and the meaning of the colours of the Irish flag. He prominently displays in his election offices a verse of a poem by John Frazier, a Presbyterian from County Offaly: “Till then the Orange lily be your badge my patriot brother. The everlasting green for me and we for one and other.”
In 1967, McMillen is involved in the formation of the Northern Ireland Civil Rights Association (NICRA) and is a member of a three-man committee which draws up the Association’s constitution. The NICRA’s peaceful activities result in violent opposition from many unionists, leading to fears that Catholic areas will come under attack. In May 1969, when asked at an IRA army council meeting by Ruairí Ó Brádaigh how many weapons the Belfast Brigade has for defensive operations, McMillen states they have only one pistol, a machine gun and some ammunition.
By August 14, 1969, serious rioting has broken out in Belfast and Catholic districts come under attack from both civilian unionists and the RUC. McMillen’s IRA command by this point still has only a limited number of weapons because the leadership in Dublin are reluctant to release guns. While he is involved in some armed actions on this day, he is widely blamed by those who established the Provisional IRA for the IRA’s failure to adequately defend Catholic neighbourhoods from Ulster loyalist attack. He is arrested and temporarily detained by the RUC on the morning of August 15 but is released shortly afterward.
McMillen’s role in the 1969 riots is very important within IRA circles, as it is one of the major factors contributing to the split in the movement in late 1969. In a June 1972 lecture organised by Official Sinn Féin in Dublin, he defends his conduct, stating that by 1969 the total membership of the Belfast IRA is approximately 120 men, and their armaments have increased to a grand total of 24 weapons, most of which are short-range pistols.
In September, McMillen calls a meeting of IRA commanders in Belfast. Billy McKee and several other republicans arrive at the meeting armed and demand McMillen’s resignation. He refuses, but many of those unhappy with his leadership break away and refuse to take orders from him or the Dublin IRA leadership. Most of them join the Provisional Irish Republican Army, when this group splits off from the IRA in December 1969. McMillen himself remains loyal to the IRA’s Dublin leadership, which becomes known as the Official IRA. The split rapidly develops into a bitter rivalry between the two groups. In April 1970, he is shot and wounded by Provisional IRA members in the Lower Falls area of Belfast.
In June 1970, McMillen’s Official IRA have their first major confrontation with the British Army, which had been deployed to Belfast in the previous year, in an incident known as the Falls Curfew. The British Army mounts an arms search in the Official IRA stronghold of the Lower Falls, where they are attacked with a grenade by Provisional IRA members. In response, the British flood the area with troops and declare a curfew. This leads to a three-day gun battle between 80 to 90 Official IRA members led by McMillen and up to 3,000 British troops. Five civilians are killed in the fighting and about 60 are wounded. In addition, 35 rifles, 6 machine guns, 14 shotguns, grenades, explosives and 21,000 rounds of ammunition, all belonging to the OIRA, are seized. McMillen blames the Provisionals for instigating the incident and then refusing to help the Officials against the British.
This ill-feeling eventually leads to an all-out feud between the republican factions in Belfast in March 1971. The Provisionals attempt to kill McMillen again, as well as his second-in-command, Jim Sullivan. In retaliation, McMillen has Charlie Hughes, a young PIRA member, killed. Tom Cahill, brother of leading Provisional Joe Cahill, is also shot and wounded. After these deaths, the two IRA factions in Belfast negotiate a ceasefire and direct their attention instead at the British Army.
When the Northern Ireland authorities introduce internment in August 1971, McMillen flees Belfast for Dundalk in the Republic of Ireland, where he remains for several months. During this time, the Official IRA carries out many attacks on the British Army and other targets in Northern Ireland. However, in April 1972, the organisation in Belfast is badly weakened by the death of their commander in the Markets area, Joe McCann. In May of that year, the Dublin leadership of the OIRA calls a ceasefire, a move which McMillen supports. Nevertheless, in the year after the ceasefire, his command kills seven British soldiers in what they term “retaliatory attacks.” McMillen serves on the Ard Chomhairle (leadership council) of Official Sinn Féin.
By 1974, a group of OIRA members around Seamus Costello are unhappy with the ceasefire. In December 1974, they break away from the Official movement, forming the Irish Republican Socialist Party (IRSP) and the Irish National Liberation Army (INLA). Some OIRA members under McMillen’s command, including the entire Divis Flats unit, defect to the new grouping. This provokes another intra-republican feud in Belfast. The feud begins with arms raids on OIRA dumps and beatings of their members by the INLA. McMillen, in response is accused of drawing up a “death list” of IRSP/INLA members and even of handing information on them over to the loyalist Ulster Volunteer Force (UVF).
The first killing comes on February 20, 1975, when the OIRA shoot dead an INLA member named Hugh Ferguson in west Belfast. A spate of shootings follows on both sides.
On April 28, 1975, McMillen is shot dead by INLA member Gerard Steenson, as he is shopping in a hardware shop on Spinner Street with his wife Mary. He is hit in the neck and dies at the scene. His killing is unauthorised and is condemned by INLA/IRSP leader Seamus Costello. Despite this, the OIRA tries to kill Costello on May 9, 1975, and eventually kills him two years later. McMillen’s death is a major blow to the OIRA in Belfast.
McKee joins Fianna Éireann in 1936. He is arrested following a raid on a Gaelic Athletic Association (GAA) club in 1938, being imprisoned in Crumlin Road Gaol for several months. Following his release from prison, he joins the Irish Republican Army (IRA) in 1939. During World War II, the IRA carries out a number of armed actions in Northern Ireland known as the Northern Campaign. He is arrested and imprisoned in Crumlin Road Gaol until 1946 for his role in this campaign. In 1956, the IRA embarks on another armed campaign against partition, known as the Border Campaign. He is again arrested and interned for the duration of the campaign. He is released in 1962.
As the 1960s proceed, McKee drifts away from the IRA. He grows very disillusioned with the organisation’s increasing emphasis on socialism and reformist politics over “armed struggle.” He is a devout Roman Catholic, who attends Mass daily. As a result, he is very uncomfortable with what he feels are “communist” ideas coming into the republican movement.
During the 1969 Northern Ireland riots, severe rioting breaks out in Belfast between Irish Catholicnationalists, Protestantloyalists, and the RUC. McKee is highly critical of the IRA’s failure to defend Catholic areas during these disturbances. On August 14, 1969, McKee, Joe Cahill and a number of other Irish Republican activists occupy houses at Kashmir Street, however, being poorly armed they fail to prevent Irish Catholics in Bombay Street and parts of Cupar Street and Kashmir Street being driven from their homes in the sectarian rioting that engulfs parts of the city. In the aftermath of the riots, he accuses Billy McMillen, the IRA’s Belfast commander, and the Dublin-based IRA leadership, of having failed to direct a clear course of action for the organization in civil disturbances. On September 22, 1969, he and a number of other IRA men arrive with weapons at a meeting called by McMillen and try to oust him as head of the Belfast IRA. They are unsuccessful but announce that they will no longer be taking orders from the IRA leadership in Dublin. In December 1969, the IRA splits into the Provisional IRA which is composed of traditional militarists like McKee, and the Official IRA which is composed of the remnants of the pre-split Marxist leadership and their followers. He sides with the Provisionals and joins the IRA Army Council in September 1970.
McKee becomes the first OC of the Provisional IRA Belfast Brigade. From the start, there is intermittent feuding between McKee’s men and his former comrades in the Official IRA, as they vie for control of nationalist areas. However, the Provisionals rapidly gain the upper hand, due to their projection of themselves as the most reliable defenders of the Catholic community.
McKee himself contributes greatly to this image by an action he undertakes on June 27, 1970, the Battle of St Matthew’s. Rioting breaks out in the Ardoyne area of north Belfast after an Orange Order parade, and three Protestants are killed in gun battles between the Provisional IRA and loyalists. In response, loyalists prepare to attack the vulnerable Catholic enclave of Short Strand in east Belfast. When McKee hears about this, he drives to Short Strand with some men and weapons and takes up position at St Matthew’s Church. In the ensuing five-hour gun battle, he is wounded and one of his men is killed, along with at least four Protestants.
On April 15, 1971, McKee, along with Proinsias Mac Airt, is arrested by the British Army when found in possession of a handgun. He is charged and convicted for possession of the weapon and imprisoned in Crumlin Road Gaol, and Joe Cahill takes over as OC of the Belfast Brigade.
In 1972, McKee leads a hunger strike protest in an effort to win recognition of IRA prisoners as political prisoners. Republicans who are interned already have special status, but those convicted of crimes do not. On June 19, the 35th day of hunger strike, he is close to death, William Whitelaw concedes Special Category Status (SCS) which, although not officially awarding political status, is tacit recognition of the political nature of the incarceration. Prisoners wear their own clothes, have no prison work, can receive one visit and food parcel per week and unlimited letters.
McKee is released on September 4, 1974, and resumes his position as OC of the Belfast Brigade. At this time the Provisional IRA calls a ceasefire, and he is involved, with Ruairí Ó Brádaigh, in secret peace talks in Derry with the Northern Ireland Office. He is also involved in talks with Protestant clergy in Feakle, County Clare, in December 1974, where he voices his desire to end the violence.
However, in the same period, McKee authorises a number of sectarian attacks on Protestants as well as renewed attacks on rival republicans in the Official IRA. For this he is heavily criticised by a group of Provisional IRA activists grouped around Gerry Adams.
A faction led by Adams manages to get McKee voted off the IRA Army Council in 1977, effectively forcing him out of the leadership of the organisation. His health suffers in this period, and he does not resume his IRA activities. He joins Republican Sinn Féin after a split in Sinn Féin in 1986. At age 89, reflecting on his involvement in the Republican cause he says, “From the time I was 15 until 65 I was in some way involved. I have had plenty of time since to think if I was right or I was wrong. I regret nothing.”
In later years McKee, Brendan Hughes and Tommy McKearney are critical of the Belfast Agreement and of the reformist politics of Sinn Féin. In 2016 he sends a message of support to the launch of the hardline new Republican party Saoradh, reportedly the political wing of the New IRA.
McKee dies in Belfast at the age of 97 on June 11, 2019. His funeral takes place on June 15, 2019, in west Belfast. His coffin is carried on a gun carriage. He is buried in Milltown Cemetery.
