Che Guevara
In Guevara's private writings from this time (since released), he displays his growing criticism of the Soviet political economy, believing that the Soviets had "forgotten Marx". This led Guevara to denounce a range of Soviet practices including what he saw as their attempt to "air-brush the inherent violence of class struggle integral to the transition from capitalism to socialism", their "dangerous" policy of peaceful co-existence with the United States, their failure to push for a "change in consciousness" towards the idea of work, and their attempt to "liberalize" the socialist economy. Guevara wanted the complete elimination of money, interest, commodity production, the market economy, and "mercantile relationships": all conditions that the Soviets argued would only disappear when world communism was achieved. Disagreeing with this incrementalist approach, Guevara criticized the "Soviet Manual of Political Economy", correctly predicting that if USSR did not abolish the law of value (as Guevara desired), it would eventually return to capitalism.
Che Guevara
As the war extended, Guevara led a new column of fighters dispatched westward for the final push towards Havana. Travelling by foot, Guevara embarked on a difficult 7-week march, only travelling at night to avoid ambush and often not eating for several days. In the closing days of December 1958, Guevara's task was to cut the island in half by taking Las Villas province. In a matter of days he executed a series of "brilliant tactical victories" that gave him control of all but the province's capital city of Santa Clara. Guevara then directed his "suicide squad" in the attack on Santa Clara, which became the final decisive military victory of the revolution. In the six weeks leading up to the battle there were times when his men were completely surrounded, outgunned, and overrun. Che's eventual victory despite being outnumbered 10:1 remains in the view of some observers a "remarkable tour de force in modern warfare".
