The 1960 Laotian coups brought about a pivotal change of government in the Kingdom of Laos. General Phoumi Nosavan established himself as the strongman running Laos in a bloodless coup on 25 December 1959. He would be himself overthrown on 10 August 1960 by the young paratrooper captain who had backed him in the 1959 coup. When Captain Kong Le impressed the American officials underwriting Laos as a potential communist, they backed Phoumi's return to power in November and December 1960. In turn, the Soviets backed Kong Le as their proxy in this Cold War standoff. After the Battle of Vientiane ended in his defeat, Kong Le withdrew northward to the strategic Plain of Jars on 16 December 1960.
