"Well, she's down, anyhow," said Chester. "That's some relief."

"And here come the Serbians," said Hal.

A handsome body of men, these Serbian cavalrymen, as they charged straight across the open field into the very jaws of death. Men fell on all sides, but those who were left did not pause. The command had gone forth that the Bulgarian guns must be silenced and the Serbians went about the work as coolly as though they had been on dress parade.

But it appeared a few moments later that the battle was not to be between horsemen and artillery, but rather between cavalry and cavalry.

From the Bulgarian lines now issued a large body of horsemen; and they came toward the Serbians at a swift gallop, their officers riding in front with swords flashing and urging their men on with words of encouragement.

The Serbian cavalry, at a command, halted and braced to receive the shock.

"Great Scott! What did they stop for!" exclaimed Hal. "They are giving the other fellows, all the advantage when they come together."

"Looks like bad generalship to me," Chester agreed.

Now, at a command from their officer, the Serbians resumed their charge; but the damage had been done and when the long lines of opposing horsemen came together the very impetus of the Bulgarian charge carried them through. The Serbians reeled, staggered and their line broke.

The Bulgarian horse plowed in among them, cutting, slashing and stabbing. Individually, the Serbians fought as bravely as their foe, but in spite of the desperate work the Bulgarian cavalry retained its cohesion and pushed steadily on.
