La Ronde de nuit
Prior to the formation of a unified police force, the colony of Tasmania (then called Van Diemen's Land) was policed from 1803 under the administration of Lieutenant Governor David Collins by a small number of superintendents and overseers, and from 1804 by a civilian body known as the "Night Watch", brought by Collins from Port Phillip Bay. The Night Watch was disbanded in 1806 due to ineffectiveness and was replaced by British military patrols. A municipal police force was established at Port Dalrymple (Launceston) on 19 November 1804, with Thomas Massey as Chief Constable.
