 Violence reached a peak on 12 August 1969 , culminating in the Battle of the <unk> — a three @-@ day pitched battle between residents and the <unk> . On 14 August units of the British Army were deployed at the edge of the <unk> and the <unk> were withdrawn . The Derry Citizens Defence Association ( <unk> ) declared their intention to hold the area against both the <unk> and the British Army until their demands were met . The British Army made no attempt to enter the area . The situation continued until October 1969 when , following publication of the Hunt Report , military police were allowed in .
