Castor and Pollux Castor and Pollux Castor and Pollux (or in Greek, Polydeuces) were twin half-brothers in Greek and Roman mythology, known together as the Dioscuri. Their mother was Leda, but they had different fathers; Castor was the mortal son of Tyndareus, the king of Sparta, while Pollux was the divine son of Zeus, who seduced Leda in the guise of a swan. Though accounts of their birth are varied, they are sometimes said to have been born from an egg, along with their twin sisters Helen of Troy and Clytemnestra. In Latin the twins are also known as the Gemini (literally "twins")
Operation Pollux Operation Pollux Operation Pollux was a military operation during the First Indochina War by the French forces in northwest Vietnam in November and December 1953 was one of a twin operation, the other being Operation Castor. The names of these operations are based upon the mythological twins, Castor and Pollux. Operation Castor recaptured and then established a fortified airfield in Điện Biên Phu, in the north-west corner of Vietnam. Operation Pollux was the name of the second operation (the evacuation of Lai Châu to Dien Bien Phu), which took place weeks later. These operations were developed by General Navarre who
