About nine o'clock one black ball was run up to the fore of the _Agamemnon_ and a gun was fired to enforce attention to the signal. This meant, "Divisions of boats to assemble round ships for which they are told off, to disembark infantry and artillery." In an instant the sea was covered with a flotilla of launches, gigs, cutters, splashing through the water, some towing flats, and the large Turkish boats, others with horse-floats plunging heavily after them. They proceeded with as great regularity as could be expected to their appointed ships, and the process of landing commenced. Up to this moment not an enemy was to be seen; but as the boats began to shove off from the ships, five horsemen slowly rose above the ridge on the elevated ground, to the right of the strip of beach which separated the salt-water lake from the sea in front of us. After awhile four of them retired to one of the tumuli inland opposite the French fleet. The other retained his position, and was soon the cynosure of all neighbouring eyes. The Russian was within about 1100 yards of us, and through a good telescope we could watch his every action. He rode slowly along by the edge of the cliff, apparently noting the number and disposition of the fleet, and taking notes with great calmness in a memorandum book. He wore a dark green frock-coat, with a little silver lace, a cap of the same colour, a sash round his waist, and long leather boots. His horse, a fine bay charger, was a strange contrast to the shaggy rough little steeds of his followers. There they were, "the Cossacks," at last!--stout, compact-looking fellows, with sheepskin caps, uncouth clothing of indiscriminate cut, high saddles, and little fiery ponies, which carried them with wonderful ease and strength. Each of these Cossacks carried a thick lance of some fifteen feet in length, and a heavy sabre. At times they took rapid turns by the edge of the cliff in front of us--now to the left, now to the rear, of their officer, and occasionally they dipped out of sight, over the hill, altogether. Then they came back, flourishing their lances, and pointed to the accumulating masses of the French on their right, and more than half-a-mile from them, on the shore, or scampered over the hill to report progress as to the lines of English boats advancing to the beach. Their officer behaved very well. He remained for an hour within range of a Minié rifle, and making a sketch in his portfolio of our appearance, we all expected she was going to drop a shell over himself and his little party. We were glad our expectations were not realized, if it were only on the chance of the sketch being tolerably good, so that the Czar might really see what our armada was like.
