On 2 July, Sheikh Bashir collected 25 of his followers in the town of Wadamago and transported them on a lorry to the vicinity of Burao, where he distributed arms to half of his followers. On the evening of 3 July the group entered Burao and opened fire on the police guard of the central prison in the city, which was filled with prisoners arrested for previous demonstrations. The group also attacked the house of the district commissioner of Burao District, Major Chambers, resulting in the death of Major Chamber's police guard before escaping to Bur Dhab, a strategic mountain south-east of Burao, where Sheikh Bashir's small unit occupied a fort and took up a defensive position in anticipation of a British counterattack.
