"Don't know what is coming over Stubbs," said Chester. "He didn't use to be as bad as that."
"He was when we first met him," Hal replied. "But he seemed to be getting over it. He's worse than ever now."
From their position, those upon the roof of the house could witness the effect of some of the great shells that were hurled into the opposing lines. One, from the Serbians, struck squarely upon the Bulgarian first line troops, doing terrible execution. Men were mowed down in great numbers.
A few moments later the Bulgarians also found the range and the havoc was frightful on each side.
"They can't stand that very long," said Hal. "One side or the other will have to make a move."
The lad was right; and as it transpired the first move was to be made by the Serbians.
So suddenly that it appeared the work of magic, a great body of horsemen, stretching out for perhaps half a mile, issued from the Serbian line in a charge. On they came, their sabers flashing in the early morning sun, straight for the distant Bulgarian line.
Chester gave an exclamation of dismay.
"They'll pass within a short distance of us," he ejaculated. "Then the Bulgarians will turn their big guns on us." He turned to Helen. "You would better go downstairs, Miss Ellison," he said quietly.
"But I want to see the battle," the girl protested.
