De Mevius, Baron
Colonel in the Sikh Army
Also known as Frank Ernest Mevins, was a Prussian who came to the Punjab in March 1827 and was employed in the Sikh army in the rank of colonel. According to the Khalsa Darbar records, Mevius had to sign a pledge that he would, "during his period of service, abstain from eating beef, smoking or shaving, would domesticate himself in the country by marriage, would never quit the service without formal permission from the Maharajah, and would engage to fight any nation with whom the Maharajah declared war, even should it be his own."
These were the usual conditions under which foreigners were admitted into Sikh service. Once Mevius was charged with using a whip against a Sikh soldier which led to a revolt in his command and he was compelled to take refuge in the Maharaja’s tent. Ranjit Singh saved his life, but refused to retain him in service. He was given his discharge in 1830.
