The scouts reported every hour to keep them on course when line of sight became impossible for the main force. The winter night was coming quickly and Pompey waited with growing impatience for the enemy legions to call a halt.

“If they don’t stop soon, they will be spending the night in the open,” Pompey said irritably. “Half of them will freeze to death.”

He squinted through the shadows of trees into the distance, though there was nothing visible. The enemy had vanished in the gloom, but the most distant of the scouting riders still reported their progress back down the line. Pompey clenched his jaw against the cold and wondered if this too was a test. Perhaps Julius was hoping to lose them, or simply march them to death over the Greek plains.

“They may have already prepared a camp, sir,” Labienus said.

His lips were numb and he knew Pompey would have to let the men rest or start seeing them drop. He smothered any sign of his irritation as Pompey rode on as if unaware of the suffering of those around him. He did not want to prompt his commander, but if they did not make camp soon they risked losing the edge they had worked so hard to gain.

The sound of galloping hooves distracted both men from their thoughts and the cold. “They have halted, sir!” the scout reported. “A small party are riding toward us.”

Pompey raised his head like a dog with a scent. “How many?” he demanded.

Even in the last gray light, Labienus could see the scout was frozen to the point of barely staying in the saddle. He moved his own horse closer and took the reins from the younger man’s stiff fingers. “Your general asked you how many were coming,” he said.

The scout blinked, summoning his wits. “Three, sir, under a flag of truce,” he replied.

“Order a hostile camp, Labienus,” Pompey said, at last. “I want high walls around us by the time they arrive. No doubt they will report every detail to Caesar on their return. Let there be nothing out of place.” He paused and straightened his back to conceal his discomfort. “Send my physician to me. I need a little of his chalk and milk to settle my stomach.”

Labienus sent men running to fulfill the order. Weary and cold as they were, the army of fifty thousand would make short work of the walled camps. It was almost second nature to them after so long in training, and he was pleased as the squares began to take shape. The sound of axes chopping into trees was as familiar as home to him, and he began to relax. Pompey had left it late, Labienus acknowledged to himself. Part of the work would be finished in the dark and there would be accidents.
