Osman Pasha and Adolphus Slade in Ottoman naval reconstruction

Osman Pasha commanded a brig at Navarino, later led an Egyptian frigate, and joined Ottoman service during the Egyptian-Ottoman War. By 1840 he commanded an Ottoman ship of the line and had risen to the Patrona rank, described here as vice-admiral. He was captured at Sinop and pictured in a Russian hospital in 1854; after returning from captivity, he remained a member of the Admiralty even though the Patrona rank was abolished. Adolphus Slade followed a different path as a Royal Navy officer who held Ottoman rank and directed naval reconstruction from 1849 to 1866. Slade's Ottoman flagship was a 72-gun frigate, an important clue to the condition of the larger fleet. Their careers brought Egyptian and British experience into Ottoman naval leadership.
