Holtz came close to the table. “They are always convenient,” with a little grimace. “What are my orders, Your Excellency?”

The General looked at him sharply. He didn’t like bitterness and he could not understand sarcasm. With an effort of will, he drew his attention to the matter in hand. “This place can be held with courage,” he said. “You will have four men. I cannot spare more. Choose whom you like. I take it you will handle the Lewis gun yourself? The enemy are unlikely to use their artillery, once they have ascertained that this place is held only by a few. Shells are costly. You are to delay them as long as possible. As long as you are alive, they cannot pass. You are not to expose yourself, and you are to be very careful not to waste ammunition. I will leave the details to you. Is there anything you do not understand?”

Holtz shook his head. “You have made it very simple, Your Excellency. How long am I to keep up the resistance?”

“I want at least twelve hours to get to the mountain road. Once I have got beyond the pass I do not think Pablo will follow any further; it would be too dangerous. We leave immediately. Pablo may not attack. In which case you will withdraw after twelve hours have elapsed from the time we leave. If he should attack, then you must hold him off until…” he glanced at the small clock on his desk, “four o’clock tomorrow.”

Holtz nodded. “I understand perfectly. If you will excuse me, I will make my preparations and choose my men.”

The General waved his hand. “I shall see you before I go,” he said. “Make your preparations with all speed.”

Outside in the courtyard there was tremendous activity. Horses were being saddled. Packs slung. Men, running to and fro, shouted orders excitedly. In the centre of the commotion stood the big, rusty field-gun. Men were already fastening thick ropes to it, and even as Holtz approached, the gun began to move slowly down the uneven road towards the distant hills.

He stood for a moment watching it go. Then he turned with a shrug of his shoulders. Time was pressing. He knew the four men he was going to choose. He knew they were reliable, although, of course, they had no wish to throw their lives away. Still, as long as he was with them, they would see it through. He was sure of that.

He caught sight of Sergeant Castra, who was walking towards him. “Sergeant,” he called. “Here, I want you.”

Castra increased his pace. He was a tall, thick-set man, with hard eyes and a firm determined jaw. He had been in the service for a long time, and Holtz knew him to be a soldier in every sense of the word.
