The entire country's military had now rebelled, with the British High Commissioner briefly detained and most of the strategic points in the capital held by the mutineers.
After appeals from the President, Julius Nyerere, the United Kingdom dispatched an aircraft carrier, HMS Centaur from Aden, with a force from the garrison there, to stand off Dar es Salaam.
After landings later that day, including a small number of armoured cars of the 16th/5th The Queen's Royal Lancers, most of the remaining mutineers had likewise surrendered; the 2nd Battalion had not been engaged, but had offered to surrender after hearing of the events in Dar es Salaam; a party of Marines travelled there and secured the barracks the next day.
Within twenty-four hours of the initial landings, and a week of the mutiny, the men of the 1st battalion were dismissed and the regiment effectively ceased to exist.
The regiment was never reformed; after the union of Tanganyika with Zanzibar later that year, the previously existing army was formally disbanded, and the Tanzania People's Defence Force was formed in September 1964, firmly under local civilian control.
