The Wind That Wrecked The Barley

For well over 800 years, the relationship between the Irish people and Britain has been tumultuous at best. It eventually culminated with the creation of a separate Irish state with the conclusion of the Irish War of Independence in 1920. However, Ireland was divided and it became a tipping point that would create numerous conflicts for years from the Irish Civil War to the IRA's Border Campaign. But no other chapter captured this than The Troubles, and it all started during the summer of 1969. In our timeline, one of the key turning points occurred in August of that year. In the aftermath of marches organized by the all-potestant, pro-Unionist Orange Order, riots broke out acrossed Northern Ireland. The worst rioting during the week took place in The Bogside neighborhood of Derry. For over 2 days straight, the residents and police battled against each other in the worst violence seen in decades, which reached such an extent that 2 turning moments occurred. First was the announcement by Irish Taoiseach Jack Lynch to send troops to the nearby border between the two nations, which Unionist feared was a potential invasion of Northern Ireland. The rioting became worse after false rumors of police attacking the local Catholic Church and led the police to use their firearms and the Royal Ulster Constabulary called upon the Special Costabulary, known as the B-Specials. The unit was almost entirely Protestant and had a history of violence against Catholics dating back to the Irish War of Independence. They were also the last men to be deployed before the British Army would intervene. Many in The Bogside feared that they would massacre them in the neighborhood. In our timeline, the B-Specials, despite violent incidents elsewhere, no major incidents, similar to Bloody Sunday occurred.

So, what if the worst case scenario occurred in The Bogside in August in 1969? What were to happen if the Irish Army intervened to end the rioting? And what happened if the Catholic fears of a massacre like Bloody Sunday occurred at the hands of the B-Specials?
