The long surges of the Gulf of Mexico were beating heavily upon the sandy beach of Point Isabel, but the dull and boding sounds were not the roar of the surf. There came a long silence, and then another boom. Each in succession entered the white tents of the American army on the upland, carrying with it a message of especial importance to all who were within. It was also of more importance to the whole world than any man who heard it could then have imagined. It spoke to the sentries at their posts, and compelled them to turn and listen. It halted all patrolling and scouting parties, making them stand still to utter sudden exclamations. More than one mounted officer reined in his horse to hear, and then wheeled to spur away toward the tent of General Zachary Taylor, commanding the forces of the United States upon the Rio Grande.
In one small tent, in the camp of the Seventh Infantry, the first boom stirred up a young man who had been sleeping, and he may have been dreaming of home. He was in the uniform of a second lieutenant, and in one respect he was exactly like all the other younger officers and most of the men of that army, for never before had they heard the sound of a hostile cannon. War was new to them, and they were not aware how many of them were now entering a preparatory school in which they were to be trained for service in a war of vastly greater proportions and for the command of its contending armies, on either side.
Up sprang the young lieutenant and stepped to the door of his tent. He was short, strongly built, and his alert, vigorous movements indicated unusual nerve, vitality, and muscular strength.
“Grant, my boy,” he muttered to himself, “that comes from the fort! The Mexicans are attacking! It’s more than twenty miles away. I didn’t know you could hear guns as far as that, but the wind’s in the right direction. Hurrah! The war has begun!”
He was only half right. The war had been begun long years before by aggressive American settlers in the Spanish-Mexican State of Texas. Now, at last, the United States had taken up the same old conflict, and only about half of the American people at all approved of it.
Grant did not linger in front of his tent. He walked rapidly away to where stood a group of officers, hardly any of them older than himself.
“Meade,” he demanded of one of them, “what do you think of that?”
“I think I don’t know how long that half-finished fort can hold out,” responded Lieutenant Meade, and half a dozen other voices instantly agreed with him as to the perils surrounding the small besieged garrison.
It was hardly possible, they said, that it could hold out until the arrival of the main army. This, too, would have to fight all the way against superior numbers, but that was a thing which it could do, and they were all wild with eagerness to be on the march, in answer to the summons of those far-away guns.
There were no railroads to speak of, and only the first small beginnings of telegraphs in the year 1846. The news of the first fighting would therefore be slow in reaching the President and Congress at Washington, so that they might lawfully make what is called a formal declaration of war. Much had already been taken for granted, but the American government was at that hour anxiously leaning southward and listening for the expected roar of Mexican cannon. It came, as rapidly as General Taylor could send it. A swift despatch-boat, with all her canvas up, went speeding across the gulf to New Orleans. Thence, in the hands of special couriers, it would gallop all the remaining distance. Meantime, the struggle at the Rio Grande frontier would continue, just as if all the legal arrangements had been made, but it would be weeks before Europe could be advised of what was going on. All this, too, when this fight over the annexation of Texas was about to lift the Republic into a foremost place among the nations. It was to give her all the Pacific coast which she now has, except Oregon and Alaska, with the gold of California and the silver of the mountains. Among its consequences were to be the terrible Civil War, the abolition of slavery, the acquisition of the Sandwich Islands, and many another vast change in the history of our country and in that of these very European nations which were then ignorantly sitting still and thinking little about it, because they had no ocean cable telegraphs to outrun the swift clipper ships.
