The Ottomans operated river gunboats on the Danube, as part of their ‘Danube gunboat flotillas’, that featured in the Russo-Turkish War of 1810. At the battle of Batin (September, 1810), the Russian army made a demonstration against the heavily defended Turkish-left with the assistance of Russian gunboats on the Danube. These gunboats caught a small Turkish flotilla, anchored close to the Turkish position on the Danube, by surprise and sank two and captured five of the vessels [1].
