One of the most important events in the era of civil rights in Northern Ireland took place in Derry, which escalated the conflict from peaceful civil disobedience to armed conflict. The Battle of the Bogside started on 12 August when an Apprentice Boys, a Protestant order, parade passed through Waterloo Place, where a large crowd was gathered at the mouth of William Street, on the edge of the Bogside. Different accounts describe the first outbreak of violence, with reports stating that it was either an attack by youth from the Bogside on the RUC, or fighting broke out between Protestants and Catholics. The violence escalated and barricades were erected. Proclaiming this district to be the Free Derry, Bogsiders carried on fights with the RUC for days using stones and petrol bombs. The government finally withdrew the RUC and replaced it with the army, which disbanded the crowds of Catholics who were barricaded in the Bogside.
