nd were threatening to pour down
on Buda-Pest and Vienna, they drove them steadily back until the first
of October, forcing them to retreat nearly three hundred miles.

In the meantime, the Balkans again became the seat of trouble. You
will recall that Bulgaria, who had grown proud because of her victory
over Turkey in the war of 1912, was too grasping when it came to a
division of the conquered territory. Thus she brought on a second war,
in the course of which Greece and Serbia defeated her, while Roumania
took a slice of her territory and the Turks recaptured the city of
Adrianople. The czar of Russia had done his best to prevent this
second Balkan war, even sending a personal telegram to Czar Ferdinand
of Bulgaria and to King Peter of Serbia, begging them for the sake of
the Slavic race, not to let their quarrels come to blows. Bulgaria,
confident of her ability to defeat Greece and Serbia, had disregarded
the Russians' pleadings, and as a result Russia did not interfere to
save her when her neighbors were robbing her of part of the land which
she had taken from Turkey.

It will be recalled that Macedonia was the country which Bulgaria had
felt most sorry to lose, as its inhabitants were largely Bulgarian in
their blood, although many Greeks and Serbs were among them.
Therefore, just as Italy strove by war and diplomacy to add Trentino

give her in case she entered the war on their side, and attacked
Turkey by way of Constantinople, while the French and English were
hammering at the forts along the Dardanelles.[7]

[7] England and France needed wheat, which Russia had in great quantities
at her ports on the Black Sea. On the other hand France and England,
by supplying Russia with rifles and ammunition, could strike a hard
blow at Germany.

The four powers, after much persuasion and brow-beating, finally
induced Serbia to agree to give up part of Serbian Macedonia to
Bulgaria. They further promised Bulgaria to give her the city of
Adrianople and the territory around it which Turkey had reconquered.
But Bulgaria was not easily satisfied. She wanted more than Serbia was
willing to give; she wanted, too, the port of Kavala, which Greece had
taken from her. This the allies could not promise.

In the meantime, Bulgaria was bargaining with Austria, Germany, and
Turkey. France, Engla
