In August 1999, East Timor voted for independence from Indonesia. Violent clashes broke out immediately between rival factions. Many civilians were killed. The International Force East Timor (INTERFET) was a multinational non-United Nations peacemaking taskforce, organised and led by Australia in accordance with United Nations resolutions to address the humanitarian and security crisis. Australian infantry and cavalry were part of Australia's contribution. Reservists from 4/19 Prince of Wales's Light Horse transitioned to full time duty to serve with regular cavalry units. INTERFET handed over control to UN peacekeepers in February 2000.
