Query: Whose message convinced much of the military to stay loyal?
Context: On the night of 23 February 1981, shortly after Antonio Tejero had stormed Congress, the Captain General of the Third Military Region, Jaime Milans del Bosch, rose up in Valencia, put tanks on the streets, declared a state of emergency and tried to convince other senior military figures to support the coup. After the televised message of King Juan Carlos I, those in the military who had not yet aligned themselves decided to remain loyal to the government, and the coup failed. Despite this lack of support, Milans del Bosch only surrendered at 5 a.m. on the next day, 24 February.
