Lord Harris's English side were touring New South Wales as part of the second England tour to Australia. The match was NSW v Harris's XI, with George Coulthard standing as one of the umpires — a Victorian by birth and a former Australian Rules footballer, employed for the tour by the English party.
Murdoch had reached 10 when Coulthard gave him out run out. The decision was contentious: Murdoch had appeared to make his ground, and the NSW pavilion erupted. Within minutes a section of the crowd — variously estimated at 1,500 to 2,000 — had broken through the boundary fence and surrounded the players. Coulthard was assaulted and had to be physically protected by Lord Harris and the Hon Edward Lyttelton.
Lord Harris himself was struck with what reports describe as 'a whip or a stick'. AN Hornby grappled with one of the rioters and emerged with his shirt torn. Play was suspended for the day.
Illegal bookmakers in the NSW pavilion, who had bet heavily on the home side, were widely blamed for inciting the trouble — England were in a winning position when Murdoch was dismissed. Inter-colonial rivalry between Victoria and NSW (Coulthard being Victorian) added fuel.
Lord Harris published an angry letter on 11 February 1879 in the Sydney press, calling the riot 'an exhibition of disgraceful larrikinism'. The NSW Cricket Association's reply, published in June, blamed Coulthard's umpiring. The exchange was reprinted across the British press and was the immediate reason MCC blocked an Australian tour to England in 1879. By 1880 the wounds had healed enough for cricket to resume — but the September 1880 Oval Test was, in part, the diplomatic settlement.
