Reinforced by land and sea, the enemy stubbornly opposed the Russians, and it was April the 7th before the Russians reached Kara Dere. Trebizond was defended by some 50000 soldiers, with whom the Breslau and other Turkish warships co-operated. After a fierce struggle the Russians forced a crossing of the river, and captured the city on April the 18th. Research Capture of Trebizond
