Practically the fate of the Russian army was decided. Lord Wolseley was in full communication with the Bulgarian General, who, with a force between forty and fifty thousand strong, had been following close upon the heels of the Russians. There could be no hope that, with their diminished and discouraged troops, the Russians would be able to defeat the English forces, against which with their intact army they had failed on the previous day. Nor could they turn on the Bulgarians without having both armies upon them at once. To avoid useless slaughter, the Russian General forty-eight hours later agreed to lay down his arms. As soon as the Russian army had given up its guns and was no longer in a position to act effectively, the English army marched back to the coast, and, according to our latest information, a considerable part of it had already embarked and sailed in an unknown direction. Lord Wolseley, with Admiral Markham and their Staffs, have returned to Constantinople, doubtless in order to be in communication with Ministers at home, the Ambassador, the Sultan, and other sources of information. It is only fair to a gallant enemy to say that the startling success which has attended our arms is, apart from the gallantry of our soldiers and the skill of the General who led them, to be attributed to the enormous advantage which is possessed by the Power that commands the sea. From the moment that our fleet cut off the communications of the Russian Army, the Russian General was in a position, such as in our time can rarely happen, of being completely deprived of all means of knowing what his enemy was doing, while, on the other hand, our own Commander was able to obtain information far more accurate than is common in war of everything that his opponent did. No other Power in Europe could have reached and destroyed with the same ease and certainty that dangerous Russian force, susceptible of indefinite increase, as long as Russia held the sea. Meantime, speculation is rife as to the direction in which our army is next going to strike. ENTHUSIASM IN CAIRO. DEPARTURE OF THE ENGLISH TROOPS.
