When James Edward Alexander served in Burma , he made in November 1825 the following valuable notes dealing with so-called warboats belonging to the king of Burma .
P. 20: "The main arm of his Majesty of the Golden Feet is his marine establishment, consisting of war-boats: every rua, of village, on the banks of the river, is compelled to furnish a certain number. The common length of these boats (which in the native language are called tee-lee) is fifty or sixty feet. They are rowed or paddled by thirty or forty men, their weapons placed at their side; they carry also a few soldiers, with a piece of ordnance mounted on the prow, which is made sharp, for the purpose of running down and staving smaller craft. Our man-of-war boats could never get near them: the steam-boat alone tired out the rowers, and when she came up with them they jumped overboard."
