"Knowledge of the great operations of war can be acquired only by experience and by the applied study of the campaigns of all the great captains. Gustavus, Turenne, and Frederick, as well as Alexander, Hannibal, and Cæsar, have all acted on the same principles. To keep one's forces together, to bear speedily on any point, to be nowhere vulnerable,--such are the principles that assure victory."--NAPOLEON. Despite the menace to Russia contained in the British Note of May 1, 1877, there was at present little risk of a collision between the two Powers for the causes already stated. The Government of the Czar showed that it desired to keep on friendly terms with the Cabinet of St. James, for, in reply to a statement of Lord Derby that the security of Constantinople, Egypt, and the Suez Canal was a matter of vital concern for Great Britain, the Russian Chancellor, Prince Gortchakoff, on May 30 sent the satisfactory assurance that the two latter would remain outside the sphere of military operations; that the acquisition of the Turkish capital was "excluded from the views of His Majesty the Emperor," and that its future was a question of common interest which could be settled only by a general understanding among the Powers[129]. As long as Russia adhered to these promises there could scarcely be any question of Great Britain intervening on behalf of Turkey. [Footnote 129: Hertslet, vol. iv. p. 2625.] Thus the general situation in the spring of 1877 scarcely seemed to warrant the hopes with which the Turks entered on the war. They stood alone confronting a Power which had vastly greater resources in men and treasure. Seeing that the Sultan had recently repudiated a large part of the State debt, and could borrow only at exorbitant rates of interest, it is even now mysterious how his Ministers managed to equip very considerable forces, and to arm them with quick-firing rifles and excellent cannon. The Turk is a born soldier, and will fight for nothing and live on next to nothing when his creed is in question; but that does not solve the problem how the Porte could buy huge stores of arms and ammunition. It had procured 300,000 American rifles, and bought 200,000 more early in the war. On this topic we must take refuge in the domain of legend, and say that the life of Turkey is the life of a phoenix: it now and again rises up fresh and defiant among the flames.
