the mountains, with Castro using his columns in a pincer movement to surround the main army concentration in Santiago. By November, Castro's forces controlled most of Oriente and Las Villas, and divided Cuba in two by closing major roads and rail lines, severely disadvantaging Batista. The US instructed Cantillo to oust Batista due to fears in Washington that Castro was a socialist, which were exacerbated by the association between nationalist and communist movements in Latin America and the links between the Cold War and decolonization. By this time the great majority of Cuban people had turned against the Batista regime. Ambassador to Cuba, E. T. Smith, who felt the whole CIA mission had become too close to the MR-26-7 movement, personally went to Batista and informed him that the US would no longer support him and felt he no longer could control the situation in Cuba. General Cantillo secretly agreed to a ceasefire with Castro, promising that Batista would be tried as a war criminal; however, Batista was warned, and fled into exile with over US$300,000,000 on 31 December 1958. Cantillo entered Havana's Presidential Palace, proclaimed the Supreme Court judge Carlos Piedra to be president, and began appointing the new government. Furious, Castro ended the ceasefire, and ordered Cantillo's arrest by sympathetic figures in the army. Accompanying celebrations at news of Batista's downfall on 1 January 1959, Castro ordered the MR-26-7 to prevent widespread looting and vandalism. Cienfuegos and Guevara led their columns into Havana on 2 January, while Castro entered Santiago and gave a speech invoking the wars of independence. Heading toward Havana, he greeted cheering crowds at every town, giving press conferences and interviews. Castro reached Havana on 9 January 1959. Provisional government: 1959 At Castro's command, the politically moderate lawyer Manuel Urrutia Lleó was proclaimed provisional president but Castro announced (falsely) that Urrutia had been selected by "popular election". Most of Urrutia's cabinet were MR-26-7 members. Entering Havana, Castro proclaimed himself Representative of the Rebel Armed Forces of the Presidency, setting up home and office in the penthouse of the Havana Hilton Hotel. Castro exercised a great deal of influence over Urrutia's regime, which was now ruling by decree. He ensured that the government implemented policies to cut corruption and fight illiteracy and that it attempted to remove Batistanos from positions of power by dismissing Congress and barring all those elected in the rigged elections of 1954
