After allowing some little time to elapse for the men to get into position, John blew his horn. A moment, and cries and shouts were heard along the whole Roman line. The sound of chopping instantly ceased, and the Roman trumpets blew to arms.
John had advanced sufficiently near to see the Roman workmen before he gave the signal. Jonas was a little in advance of him and, as the horn sounded, he saw him step out from behind a tree, whirl his sling round his head and discharge a stone and, almost simultaneously, a Roman sentinel, some forty paces away, fell with a crash upon the ground.
The Roman soldiers who had retained their armor ran instantly forward, to support their sentries. The others hastily buckled on their breastplates, caught up their bucklers and helmets, and joined their comrades. Arrows continued to fall among them from their invisible foes and, although most of these fell harmless from their armor, several soldiers fell, in addition to the seven or eight who had been killed by the first volley.
The centurion in command soon saw that the number of his assailants was small but, afraid of being drawn into an ambush, he hesitated to give orders for an advance; but dispatched a messenger instantly to camp, contenting himself with throwing out strong parties a hundred yards in advance of his line. These now became the objects of attack, while arrows ceased to fall among the main body of the troops.
John moved round the flank, till he gained a position whence he could observe the camp. The trumpets above had been heard there, and the troops had already taken up their position under arms. As he looked on, he saw the messenger run up to a party of mounted officers. A minute later a trumpet sounded, and a strong body of Arabian archers advanced, at a run, up the slope. John at once withdrew to his first position, and sounded the order for instant retreat; and then, hurrying back half a mile, sounded the note for his followers to assemble at the spot where he was standing.
In a few minutes, all had joined him. They were in high spirits at the success of this first skirmish; and wondered why they had been so suddenly called off, when the Romans had shown no signs of advancing against them.
"There are fully a thousand Arab archers in the forest, by this time," John said. "They are as fleet of foot as we are, and it would be madness to remain. We have stopped their work, for a time; and have killed many, without a scratch to ourselves. That is well enough, for today. Tomorrow we will beat them up, again."
At daybreak, two of the party were sent forward to the edge of the wood, to see with what force the Romans went out to work. They brought back the report that they were accompanied by a strong body of archers; and that, as soon as they reached the forest, the archers were scattered in front of them for a long distance, and that it would be impossible to approach them, unobserved.
On the previous afternoon, John had dispatched Jonas to Abila, and he had returned with a number of cows' horns. Round the fire in the evening, the men had set to work to pierce the points with heated arrowheads, and had converted them into instruments capable of giving a deep, prolonged sound. On the return of the scouts, John set his men in motion.
"We cannot fight them, today, but we can hinder their work. We will scatter through the forest and, as we approach them, each is to sound his horn; and continue to do so, from time to time. The Romans will think that a great force is advancing against them."
