What really sent James Dutton to the war? Had he some unformulated and hitherto unsuspected dream of military glory, or did he have an eye to supposable gold ingots piled up in the sub-basement of the halls of the Montezumas? Was it a case of despised love, or was he simply tired of re-heeling and re-soling the boots of Rivermouth folk; tired to death of the river that twice a day crept up to lap the strip of sandy beach at the foot of Nutter's Lane; tired to death of being alone, and poor, and aimless? His motive is not positively to be known, only to be guessed at. We shall not trouble ourselves about it. Neither shall the war, which for a moment casts a lurid light on his figure, delay us long. It was a tidy, comfortable little war, not without picturesque aspects. Out of its flame and smoke leaped two or three fine names that dazzled men's eyes awhile; and among the fortunate was a silent young lieutenant of infantry--a taciturn, but not unamiable young lieutenant--who was afterward destined to give the name of a great general into the keeping of history forever. Wrapped up somewhere in this Mexican war is the material for a brief American epic; but it is not to be unrolled and recited here. II With the departure of Our Country's Gallant Defenders, as they were loosely denominated by some--the Idiots, as they were compactly described by others--monotony again settled down upon Rivermouth. Sergeant O'Neil's heraldic emblems disappeared from Anchor Street, and the quick rattle of the tenor drum at five o'clock in the morning no longer disturbed the repose of peace-loving citizens. The tide of battle rolled afar, and its echoes were not of a quality to startle the drowsy old seaport. Indeed, it had little at stake. Only four men had gone from the town proper. One, Captain Kittery, died before reaching the seat of war; one deserted on the way; one, Lieutenant Bangs, was sent home invalided; and only James Dutton was left to represent the land force of his native town. He might as well have died or deserted, for he was promptly forgotten.
