He resigned his clerkship. He recalled his money from Canada, and considerably increased at least its nominal amount by converting the gold into greatly depreciated greenbacks. With this capital he opened a commission and forwarding house at Cairo, together with a coal yard, a bank, five wharf boats, half a dozen tugs, an insurance office, a flour mill, and other things. He sent for his brothers to act as his clerks and presently to become his partners. From the beginning he made money rapidly, and from the beginning he was eagerly on the lookout for opportunities, which in that time of rapid change were abundant. He quickly secured control of nearly all the commission and forwarding business that centered at Cairo. By underbidding the government itself he presently had contracts for all the vast government business of that character. He was always ready to take up a collateral enterprise that promised results. When the Mississippi River was reopened to commerce by the fall of Vicksburg and Port Hudson, Captain Will Hallam was the first to see and seize the opportunity. He bought everything he could lay his hands on in the way of steamboats and barges, and sent them all upon trading voyages--each under charge of a captain, but each directed by his own masterful mind--up and down the Mississippi, and up and down the Ohio, and up and down every navigable tributary of those great rivers. This field was quickly made his own, so far as he cared to occupy it. If a rival attempted a competition that might hurt his enterprises, Captain Hallam quietly and quite without a ripple of anger in his voice, dictated some letters to his secretary. Then freight rates suddenly fell almost to the vanishing point, and after a disastrous trip or two, his adversary's steamboats became his own by purchase at low prices, and freight rates went up again. He bore no enmity to the men who thus antagonized him in business and whom he thus conquered. His attitude toward them was precisely that of a soldier toward his enemy. So long as they antagonized him he fought them mercilessly; as soon as they fell into his hands as wounded prisoners, he was ready and eager to do what he could for them. Those of them who knew the river, and had shown capacity in business, were made steamboat captains in his service, or steamboat clerks, or wharf-boat managers, or agents, or something else--all at fair salaries. It was Captain Will Hallam's practice to make partners of all men who might render him service in that capacity. Thus when he saw how great a business there must be at Cairo in supplying Pittsburg steam coal to the government fleets on the Mississippi, and to the thousands of other steamboats trafficking in those waters, he went at once to Pittsburg and two days later he had made a certain Captain Red his partner in the control of that vastly rich trade.
