Orangemen Civilian casualties: The Harbour Grace Affray was an armed conflict of religious violence that happened on Saint Stephen's Day, 1883 in the town of Harbour Grace, Colony of Newfoundland, between members of the Loyal Orange Association and the Roman Catholics.

[1] In 1883, the Loyal Orange Association in Harbour Grace decided to postpone the events of their commemoration of Protestant victory over the Catholics at the Battle of the Boyne, from 12 July to Saint Stephen's Day.

On Saint Stephen's Day, 400 to 500 Protestants marched down Harvey Street of Harbour Grace in celebration.

As a result, Governor John Hawley Glover had the HMS Tenedos anchored in Harbour Grace and an additional 50 police constables stationed to keep law and order.

[4] The events of the affray and subsequent trials lead to the fall of Newfoundland Premier, Sir William Whiteway's Government in 1885.
