RUSSIA DECLARES WAR AGAINST ENGLAND.

SIR GEORGE TRYON EVACUATES THE BLACK SEA.

London, May 21.

Events have ripened fast since last week. Russia, on May 16, on hearing of the dispatch of our troops to the East, declared war against us. The excitement against us in France has reached boiling point. There can be no doubt that our great fleet of convoys would not have been allowed to leave England had there, at the time of their departure, seemed to be any prospect of France declaring war against us, because from Algeria and her southern ports, she so threatens our movement through the Mediterranean that that opportunity is in itself an additional incentive to her to declare war. For a long time, however, it appeared as if the Ministry, prudently anxious not to add further to the enemies France already has on her hands, would temporise with us. Public feeling will, however, it is to be feared, prove too strong for the Ministry, and for some time the gravest anxiety was felt at home as to the fate of the expedition in the event of the fleet being attacked whilst escorting so great a convoy of ships, while Sir George Tryon was known to be fully occupied in the Black Sea. On the 18th, however, a telegraphic message arrived announcing that Sir George Tryon had withdrawn the entire fleet from the Black Sea immediately after the retreat of the Russian Fleet to Sebastopol; that his flag-ship had arrived at Malta, that the Duke of Connaught, in the Orient, had reached Cyprus after a very rapid and successful voyage; and that all the transports sailing direct from England had either arrived at or passed Malta. It is understood that the greater part of the troops of the 1st Army Corps will for the present rendezvous at Cyprus, where extensive preparations have for a long time past been made for their reception. Alarm was at first excited in some quarters lest the troops should suffer as they had done at the time of the first occupation of Cyprus. But according to the reports from the island it appears that a great improvement has taken place in its sanitary condition—thanks to the British occupation; that the chief cause of the ill-health of the troops at the former time was the want of proper hutting arrangements, provided for them beforehand. Large quantities of roofing felt have been sent out, and labourers have constructed, under the direction of the engineers, large huts admirably roofed, and now practically ready for about 30,000 men. In case the necessary huts should not be ready for the whole of the troops, it is understood that the remainder of the force will land in Egypt. It is obvious that no expedition can be carried into the Black Sea until the great Naval action, which will almost certainly follow the French Declaration of War,—which is expected whilst we write,—has decided which flag is to be supreme in the Mediterranean.

Meantime, Sir Evelyn Wood’s troops, which sailed from Antwerp on May 13th and 14th, have temporarily put into Gibraltar and Cadiz, where they have been received in the most friendly manner by our present allies the Spaniards.

The departure from England of the second half of the 2d Corps has been postponed. The ships are ready, but it is obviously inadvisable to accumulate more troops on the long line to the East till the question of the supremacy of the Alliance in the Mediterranean has been settled. The detachment of troops which was landed at Trebizonde has necessarily been withdrawn. They would have been exposed to attack by indefinitely superior force as soon as the command of the Black Sea passed into the hands of the Russians. It appears that the detachment never consisted of more than half a battalion, and a few sappers from the garrison of Cyprus, which had been reinforced with a view to such a movement.
