1516 – 29 August 1542), anglicised as Christopher da Gama, was a Portuguese military commander who led a Portuguese army of 400 musketeers on a crusade in Ethiopia and Somalia (1541–1543) against the far larger Adal Muslim army of Imam Ahmad ibn Ibrahim al-Ghazi (also known as Ahmad Gragn) aided by the Ottoman Empire.
He, along with the allied Ethiopian army, was victorious against larger forces in four battles, but was seriously wounded in his last battle and was captured, tortured, and executed.
Sir Richard Burton, in his First Footsteps in East Africa, referred to him as "the most chivalrous soldier of a chivalrous age."
