Thus cut off for the moment from effective intervention on the Danube, the British Government drifted towards that tremendous Dardanelles enterprise[67] which took the place of the Serbian proposal. The first bombardment of the Dardanelles forts (February 25th to 26th) seemed to go prosperously; and at the opening of March Russia began to do well. Once more there was a new twist in the designs of the Greek Crown Government; and on March 6th the Crown Council assembled at Athens offered the whole Greek fleet and one Greek division for co-operation in the attack on the Dardanelles. But already the curt refusal of the previous overtures had driven the Allies to other designs; and the pro-Bulgarian influences in Russia were now very strong. Bulgaria was now astutely offering to lend her armies for an attack on Constantinople from the north-west while the fleets were hammering at the Straits. The old Russian Court Government, always fearful of Greek designs on Constantinople, leaned towards Bulgaria, and, now that a choice seemed possible, preferred Bulgarian help to Greek. As far as we can peer through the mists of Balkan intrigue, the success of the earlier bombardments of the Dardanelles outer forts swung Bulgaria for the time away from her Teutonic bearings. She was for the moment inclined to join the Entente, if only from fear of the consequences.[68] Whether she had signed an agreement with Germany or not, does not seem to have troubled the statesmen at Sofia, and certainly not the King.[69] The sanctity of a treaty would probably not have affected the policy of a country already strongly bitten with the virus of Prussia’s world-politics. Bulgaria was, in fact, during that time making offers to both sides; she was, in vulgar language, waiting to see “how the cat jumped.” For the moment, therefore, she became “pro-Entente.” But immediately that the failure of the Dardanelles attack became apparent she swung back into the Teutonic orbit. The diplomatic situation was, as Lord Grey fairly claimed,[70] “overshadowed by the military.” Deeply disappointed with Greece, Mr. Lloyd George now held aloof from her overtures, and was inclined, for the moment, to hope something even from the Bulgarian alternative. During the spring and summer of 1915 the Russian campaign diverted the German resources for a while from the meditated attack on Serbia. The position along the Danube became less threatening. It became the German design to throw back Russia from Galicia and Poland before she entered upon her great Near Eastern enterprise. The result was a temporary lull for Serbia.
