Mehmed Ali’s ultimatum forced the Porte to remove Husrev as Grand Admiral

Evidence

Seeing that his requests to depose Husrev went unanswered, Mehmed Ali finally resorted to threat. He wrote to the Sublime Porte saying that unless Husrev were removed from the command of the navy and unless his son were given a free hand to conduct military operations as he saw best, he would ask Ibrahim to stop fighting the Greeks altogether.
