ascended on horseback. Between Bridgetown, in Barbadoes, and Kingston, Jamaica, he divided his time, and though monotonous, his life in the Windward Islands was not wholly void of adventure.

Shortly after joining his regiment at Bridgetown our hero had his first affair of honour, an opportunity to display his courage under most trying conditions. A certain captain in the 49th was a confirmed duellist, with a reputation of being a dead shot at short range. Resting upon his evil record, this braggart had succeeded in terrorizing the garrison, and it was soon Brock's turn to be selected for insult. But Isaac could not be bullied or intimidated. He promptly challenged and was as promptly accepted.

The fateful morning arrived. In a lonely spot, palm-sheltered, and within sight of the sea breaking upon the coral reefs, principals and seconds met. There was no question in Brock's mind as to his duty—the duello at that time was the recognized court of appeal. If its purpose as originally designed had at times been infamously abused, it was still the one and only arbiter through which insults had to be purged and from which, for the "officer and gentleman," there was no escape.

Now Isaac, who was several inches taller and much bulkier than the scoundrel who had insulted him, declined to become a shining mark at the regulation twelve paces. He demanded from his fire-eating antagonist that the duel proceed on equal terms. Whipping out his kerchief, cool as a cucumber, his blue eyes steady and resolute, he insisted that they both fire across it. The fairness of the proposal staggered the bully. The chances were not sufficiently one-sided. If this plan was acted upon he might himself be killed. He refused to comply. The code of honour and garrison approval sustained Brock in his contention, and the refusal of the professional killer to fight under even chances was registered in the mess-room as the act of a coward, and he left the regiment by compulsion.

In Jamaica the continued strain of inactivity under which our hero fretted told upon him, and he was struck down with fever, his cousin, Henry Brock, lieutenant in the 13th Foot, dying in Kingston of the same pestilence. At this time Isaac had as servant a soldier named Dobson, one of those faithful souls who, true as steel, once installed in their master's affection, remain loyal to the end. To the untiring attentions of this man Brock owed his life. Deep and mutual respect followed, and the two became inseparable. Where Brock went, there was Dobson, sharing his fortune and all the hard knocks of his military campaigns, a fellowship ending only with Dobson's death, shortly before his "beloved master" gave up his life on Queenston Heights.

Tropical malaria is hard to shake off. Release from duty was imperative, and as England was now calling for recruits, the War Office summoned Brock, an alluring sample of a soldier, to whom was assigned the task of licking the fighting country bumpkin—the raw material—into shape. This he did, first in England, then in Guernsey and Jersey. A vision of our hero, glorious in his uniform, was in itself sufficient to ensnare the senses of any country yokel. It was a militant age.

When quartered in Guernsey, and from the same heights of Jerbourg where but a few years before he was wont to sweep the ocean for belated fishing smacks, Brock saw his kinsman, Sir James Saumarez, and the white canvas of a small squadron, heave in sight from Plymouth Roads. The British sailor had been ordered to ascertain the strength of the French fleet. Saumarez' ships were far slower than those of the enemy, so, feigning the greatest desire to fight, he lured his opponent by a clever ruse. First he closed with him, and then, when his own capture seemed inevitable, hauled his wind, slipped through a maze of reefs by an intricate passage—long familiar to our hero—and found safety off La Vazon, where the Frenchmen dare not follow.

In June, 1795, Brock purchased his majority, but retained his command of the recruits. From toes to finger-tips Isaac was a soldier, bent on mastering every detail of the profession of his choice. A year after the return of the 49th to England, on the completion of his 28th year, he became by purchase senior lieutenant-colonel of his regiment. High honour and rapid promotion, considering that for five out of seven years' service he had remained an ensign. He had learned to recognize opportunity, the earthly captain of a man's fate.
