Konstantin's letter was shown to his brother, Tsar Alexander II, who wrote "this idea is worth considering" on the front page. Supporters of Konstantin's proposal to immediately withdraw from North America included Admiral Yevfimy Putyatin and the Russian minister to the United States, Eduard de Stoeckl. Gorchakov agreed with the necessity of abandoning Russian America, but argued for a gradual process leading to its sale. He found a supporter in the naval minister and former chief manager of the Russian-American Company, Ferdinand von Wrangel. Wrangel pressed for some proceeds to be invested in the economic development of Kamchatka and the Amur Basin. The Emperor eventually sided with Gorchakov, deciding to postpone negotiations until the end of the RAC's patent, set to expire in 1861.
