Bakunin found Marx's economic analysis very useful and began the job of translating "Das Kapital" into Russian. In turn, Marx wrote of the rebels in the Dresden insurrection of 1848 that "[i]n the Russian refugee Michael Bakunin they found a capable and cool headed leader". Marx wrote to Friedrich Engels of meeting Bakunin in 1864 after his escape to Siberia, saying: "On the whole he is one of the few people whom I find not to have retrogressed after 16 years, but to have developed further".
