General Milne was next informed that the advance would begin over again on May 8, 1917. So another assault on the enemy lines was begun between Lake Doiran and the "Petite Couronne" Hill. In spite of the powerful opposition of the Bulgarians some progress was made, and twelve days later the new advance line was consolidated. A farther advance was in progress, with every prospect of success, when on May 24, 1917, General Milne received instructions from Sarrail to cease all offensive operations.
By itself this report might at least indicate unpleasant relations between the British and the French commanders, but further significance is added by the announcement made December 19, 1917, that General Sarrail had been recalled from his supreme command on the Macedonian front, to be succeeded by General Guillemet.
A serious charge, it will be remembered, had been made against Sarrail in France before his appointment to Saloniki, in July, 1915. This charge had been made by General Dubail and had been indorsed by General Joffre and Millerand, then Minister of War in the French Cabinet. It had to do with certain maneuvers against the German Crown Prince, directed by Sarrail under the command of Dubail. Subsequently these charges were dropped, and until his sudden appointment to the Saloniki command Sarrail dropped from view.
The specific reason for Sarrail's removal has not been officially stated, but there are rumors throwing doubt on his loyalty and suggesting his connection with the Caillaux scandal, which would imply that Sarrail had deliberately made no efforts to proceed seriously against the Bulgarians and the Austrians, even that he had secretly connived in the destruction of the Rumanians when he should have created a diversion by a general attack in Macedonia.
The double part played by Constantine, King of Greece, in the dealings with the Entente Powers, had always been a matter of grave suspicion, in spite of his repeated denials and protestations of friendship, published through his frequent newspaper interviews. Even after his removal from the throne by the Allies there still remained a doubt in the minds of many people that he had been justly treated. But then his duplicity has been conclusively proved beyond all question.
