It was a little before sunset when we reached the place that Tizoc had selected for our ambush upon the promontory; and an hour later, just as the shadows of evening were beginning to fall, one of our lookout men reported that a large boat--of which the oars must be muffled, for no sound came from it--was pulling around a point just beyond where we lay. There was a little stir among our men when this news was received, and a shifting and arranging of weapons, so that all might be in readiness when the moment for opening the ambush came; but we had a picked force with us, each man of which fully understood how necessary was silence to the success of our plans, and the quick thrill of movement was so guarded that it scarcely ruffled the deep stillness of the night.
But the moments lengthened out into minutes, and the minutes slowly slipped by until a full hour had passed, and the thick darkness of tropical night was upon us, and still there was no sign of a foe. Tizoc grew uneasy, for it was evident that we were in error in our conception of the enemy's plan. Had he intend-to mount his own men as sentinels in place of our men whom he had slain, and then get save possession of the promontory by killing the relief as it came on, we should have been long since engaged with him; but here the night was wearing on, and, excepting only the boat that our scouts had seen, there had been nothing to show that the attack which we had expected so confidently was anything more than a creation of our own fears. Yet our only course was to remain where we were until morning; for some accident might have delayed the attack, and the necessity of holding the promontory was so urgent that we could not take the risk of withdrawing our force.
It was weary work sitting there in the darkness, after all the weariness of so exciting a day, and as the hours dragged on I found myself now and then sinking into a doze, for which I reproached myself; yet also excused myself by the reflection that I did not at all profess to have either the training or the instincts of a soldier, but had been brought up, as a man of peace and as a scholar, in accordance with the sound principle that night rationally is the time set apart for sleep. It was from a most agreeable nap--in which I was dreaming pleasantly of my old life in Ann Arbor--that I was roused suddenly by Rayburn's quick grip upon my shoulder, and by his sharp whisper, "What's that?"
