April, 1915, opened with an occurrence that seemed to throw a strong light on the attitude of Bulgaria. On the night of the second day of the month a large force of Bulgar Comitajis made a raid over the southeastern frontier of Serbia, and, after attacking successfully the Serbian outposts and blockhouses, in an attempt to cut the railroad, by which Serbia was getting war supplies from the Allies, they were repelled by the Serbians, though only after severe fighting. Serbia and Greece both protested loudly, but Bulgaria affirmed that she had had nothing to do with the matter. As has developed since, Bulgaria had by this time definitely decided to strike for the Teutonic allies when the right moment should come. Already back in January, 1912, a secret treaty had been negotiated between Bulgaria and Germany. This was signed a little later by Prince Buelow and M. Rizoff at Rome. There were more reasons than one for keeping this secret. For within the Bulgarian Parliament there was a strong opposition to the German policy of Ferdinand and Radoslavov, led by Malinoff, chief of the Democratic party, and Stambulovski, chief of the Agrarian party, an opposition so bitter and determined that the king had good reason to fear an open revolution should he openly declare himself for the Germans. On May 29, 1915, the Allies again sent a note to Bulgaria, making proposals which comprised the results of their efforts to obtain concessions from the other Balkan States. On June 15 Radoslavov sent a reply, asking for further information, obviously drawn up in order to gain time. Meanwhile, on June 11, Venizelos had again appeared in Athens, where he received a warm welcome from the populace, with whom he was the prime favorite. Within a few days he resumed the leadership of the Greek Liberal party and, at a general election, which was held shortly after, he showed a popular majority support of 120 seats in the Popular Assembly, notwithstanding a determined opposition made by his opponents. Before the Balkan wars the Greek Parliament had consisted of 180 members, but by according representation to the districts in Macedonia annexed after the wars the number was brought up to 316. Venizelos and his policy in favor of the Allies were emphatically indorsed by the Greek suffrage. Naturally this expression of the people's voice was a smart blow at the king and his councillors. On the other hand, they were encouraged by an unfavorable turn that was now taking place in the military operations of the Allies.
