It was a vast armada. No pen could describe its effect. Ere an hour had elapsed it had extended itself over half the circumference of the horizon. Possibly no expedition so complete and so terrible in its means of destruction, with such enormous power in engines of war and such capabilities of locomotion, was ever yet sent forth. The speed was restricted to four miles and a half per hour, but with a favouring wind it was difficult to restrain the vessels to that rate, and the transports set no sail. The course lay N.E. by E., and the fleet was ordered to make for a point 40 miles due west of Cape Tarkan. On looking to the map it will be seen that the point thus indicated is about 50 miles east of Fidonisi, or Serpents' Island, off the mouth of the Danube, and that it lies about 100 miles to the north-east of Sebastopol, Cape Tarkan being a promontory of the Crimea, 63 miles north of the fortress. It was understood that this point was the rendezvous given to our French and Turkish allies. The fleet, in five irregular and straggling lines, flanked by men-of-war and war steamers, advanced slowly, filling the atmosphere with innumerable columns of smoke, which gradually flattened out into streaks and joined the clouds, adding to the sombre appearance of this well-named "Black" Sea. The land was lost to view very speedily beneath the coal clouds and the steam clouds of the fleet, and as we advanced, not an object was visible in the half of the great circle which lay before us, save the dark waves and the cold sky. Not a bird flew, not a fish leaped, not a sail dotted the horizon. Behind us was all life and power--vitality, force, and motion--a strange scene in this so-called Russian lake! From time to time signals were made to keep the stragglers in order, and to whip up the laggards, but the execution of the plan by no means equalled the accuracy with which it had been set forth upon paper, and the deviations from the mathematical regularity of the programme were very natural. The effect was not marred by these trifling departures from strict rectilinearity, for the fleet seemed all the greater and the more imposing as the eye rested on these huge black hulls weighing down upon the face of the waters, and the infinite diversity of rigging which covered the background with a giant network.
