In 1870, Mott was made the first aide-de-camp to the Isma'il Pasha. Two years later, he also became a Grand Officer of the Imperial Order of the Osmanieh. He remained in Egyptian service until his contract expired four years later. Declining to renew it, Mott instead turned over command to Charles Stone and returned to Turkey to take part in the wars between Serbia, the Russian and Ottoman Empires. He later distinguished himself during the Battle of Shipka Pass.
