By 1920 growing
unemployment in the linen industries and engineering sector were creating tension within the "Protestant bloc". Large numbers of well organised ex-servicemen were still out of work and a cause of concern to the local
middle class. It was the local middle class who alleged that "peaceful penetration" of Belfast industry during the war by thousands of Catholics created the unemployment problem, especially that of the ex-servicemen. It would be the local middle class who succeeded in giving the conflict its
sectarian twist. Paul Collins suggests that the expulsions were partly the result of a speech made by Carson on 12 July,
Orange Order celebrations linking Labour with Sinn Féin: "…These men who come forward as the friends of Labour care no more about Labour than does the
man in the moon. Their real object, and the real insidious nature of their propaganda is that they mislead and bring about disunity amongst our own people and in the end before we know where we are, we may find ourselves in the same bondage and slavery as is the rest of Ireland in the South and West." Collins however suggests that the direct cause of the expulsions was the killing of
Banbridge RIC man Colonel Smyth on 7 July in
Cork. Rail Union members in the south of Ireland refused to allow his body to travel home by train, leading many Loyalists to then identify the Labour movement with his assassins. It was on the day of his funeral, Collins says, that the expulsions began, resulting in ten thousand Catholics and so-called "Rotten Prods" with connections to Labour. Most Protestant employers looked on with tacit approval as "Vigilance Committees" were established to prevent "disloyalist" workers from being re-employed. Protestant domination of the Belfast industries was celebrated with Union Jack unfurlings and addressed by members of the UULA. ==B Specials established==
