For a while he paced up and down the platform, trying to overcome his drowsiness, as he took up his watch, and finally he sat down on one of the guns, feverishly awaiting the signal to prepare for the coming struggle; for he was unaware of any change in the orders given.

Suddenly he heard rapid footsteps coming toward him, and Colonel Lopez, recognizable in the dark by his uniform embroidered in silver, stood before him, followed at a short distance by a body of soldiers. Pointing to these, he said: "Here is a reinforcement of infantry. Arouse your artillerymen; have this gun taken out of its embrasure and turned obliquely to the left—quickly."

Believing that the time for the sortie had come, the lieutenant promptly called his men, while Colonel Lopez stood by impatiently, upbraiding in forcible terms the old sergeant, who, just aroused from his first sleep, was slow to obey. After repeating his orders, he hastily withdrew.

The lieutenant was surprised at the strange instructions given him, and although he reflected that the colonel must have good reasons for the command,—probably some cause to fear an attack on this point,—he instinctively felt a misgiving.

The platoon of infantry brought by Colonel Lopez had taken its stand behind the battery. After carrying out the colonel's orders, the lieutenant looked for his sword and his zarape, left by him on the ground where he had lain. They were missing. Suspecting the newcomers, he called their officer's attention to the fact. Then for the first time he noticed the strange demeanor of his new companions. The officer was utterly unknown to him. He seemed uncommunicative. There was something particularly unfamiliar in the men's appearance. Yet as a number of companies in the imperial army had been formed with city recruits or even with prisoners taken in the sorties during the siege, this alone would not have warranted serious suspicion. But when one of his artillerymen came up to him excitedly and complained that his musket had been taken from him, and when this complaint was promptly followed by another, he again went to the officer and inquired to what corps he and his men belonged. Without a moment's hesitation the stranger answered that he formed part of General Mendez's brigade.

Lieutenant Hans had long served in this brigade and knew all its officers. His doubts were at once aroused. The conviction gradually grew upon him that something unusual was taking place, and again he begged the officer to tell him the real cause of his presence at this post. The man answered that news had come that one of the battalions of the garrison of La Cruz had agreed to betray the place, but that fortunately the conspiracy had been discovered, and that all the posts were now being changed. This story tallied with the haste and peculiar manner of Colonel Lopez, the commander of the place, as well as with the unusual stir now visible farther along the line toward the pantheon. Anxious, however, to get at the truth, the lieutenant resolved to join the colonel, and asked the officer the direction which he had taken. The stranger silently pointed toward the pantheon.

As the lieutenant proceeded to descend from the terrace, a sentry, hitherto unnoticed, roughly stopped him, crying, "Halt, there!" The man evidently had his orders, and the lieutenant turned to the strange officer, requesting him to suspend them in his favor. The latter, however, evaded the question. This irritated him, and noticing just then a man holding one of the missing muskets, he attempted to tear it away from him, whereupon the soldier attacked him with his bayonet, and things might have gone hard with Lieutenant Haus had not the strange officer interfered.

"But," exclaimed the young man, "will you tell me what on earth is going on here?" "Do not worry," reiterated the strange officer." The truth is that we are part of General Quiroga's brigade. We have just returned from Mexico with General Marquez to relieve the place."

The palpable falsehood was enough to excite the young man's worst fears. General Quiroga, it was well known, had left his infantry at Queretaro. Moreover, it was quite impossible for troops to enter the closely besieged place without being heard and recognized by the besiegers. Something like the truth flashed through his brain. And yet how was he to account for the presence and words of Colonel Lopez, whose interest, as well as every tie of duty and gratitude, must bind him to the Emperor? In his bewilderment he exclaimed: "Amid so many falsehoods, I suspect treason." After a moment's hesitation the strange officer replied: "Have no fear, senor; you are in the hands of the regular army. We are not guerrilleros; we belong to the battalion of the supremos poderes of the republic."

For a moment the lieutenant stood petrified. The whole truth, in all its hideousness, burst upon him. The enemy was in possession of the place. What horrors would come next? And yet, Colonel Lopez—was it a hallucination? Could he have mistaken his identity in the darkness of the night? He called the old sergeant and asked him if he had recognized the colonel. "Yes," replied the sergeant, who, having been roughly handled by their superior officer, had good reason to remember.
