In the Fall of 1812, Johnson made a contract with the County Commissioners, Messrs. Wright, Ruggles and Miles, to build a Court House and Jail on the Public Square, opposite where the First Presbyterian Church now stands. The material was to be logs, laid end-wise for greater security. The work was pushed forward rapidly the next Summer, and towards noon of September 12th, Johnson and his men were just putting the finishing touches to the building, when they were startled by what seemed the roar of distant thunder. On looking out of the windows not a cloud could be seen in the sky, but the reverberations continued, and at once the conviction that the noise was of cannons seized them. Throwing down their tools they ran to the bank of the lake, where nearly all the villagers at home to the number of about thirty, were already gathered, stretching their eyes to the westward, whence the sounds came. Now the reports of the cannon could be plainly distinguished. They knew that Perry's fleet had passed up the lake, and that, consequently, a battle could be at any moment expected. The louder reports told when the Americans fired, for their guns were of heavier caliber than the English. At last the firing ceased for a while. Then three loud reports, evidently American, were heard, and the little crowd, convinced that their side had won, gave three hearty cheers for Perry.
About two days afterwards, Johnson and a man named Rumidge picked up a large flat-boat that had been built by General Jessup for the conveyance of troops, and then abandoned. Each of the finders purchased a hundred bushels of potatoes, took them to the army at Put-in-Bay, quadrupling the money invested, and giving Johnson his first financial start in life.
As General Jessup needed the boat to transfer his troops to Malden, he retained it, taking Rumidge also into service, and leaving Johnson to return to Cleveland on the gunboat Somers, of which he was made pilot for the voyage. Shortly afterwards Rumidge returned with the boat and brought news that the American forces had fought a battle with the British at Moravian Town. Johnson resumed command of the flat-boat, and with his associate freighted it with supplies for the army at Detroit. The speculation was successful, and Johnson engaged with the quartermaster of the post to bring a cargo of clothing from Cleveland to Detroit. The season was far advanced, and the voyage was cut short by the ice in the upper part of the lake, so that the boat was headed for Huron, where the cargo was landed and the freight for that distance paid.
Johnson was now a man of means, the successful transactions with the army having given him more money than he had ever possessed at one time before. His voyages and trading success had given him a taste for similar occupations in the future, and his first step was to build a vessel for himself. His first essay in ship-building was something novel. The keel was laid for a ship of thirty-five tons, to be named the Pilot. There was no iron for spikes, but wooden pins supplied their place. Other devices of similar primitiveness were resorted to in the course of the work, and at last she was finished. Now came the question of launching, and it was not lightly to be answered. Modern builders sometimes meet with a difficulty owing to the ship sticking on the "ways," but this early ship-builder of Cleveland had a greater obstacle than this to overcome. He had built his ship with very slight reference to the lake on which she was to float. For convenience in getting timber, and other reasons, he had made his ship-yard about half a mile from the water, near where St. Paul's Church now stands on Euclid avenue, and the greasing of the "ways" and knocking out of the blocks would not ensure a successful launch. Here was a dilemma. Johnson pondered and then resolved. An appeal for aid was promptly responded to. The farmers from Euclid and Newburgh came in with twenty-eight yoke of cattle. The ship was hoisted on wheels and drawn in triumph down the main street to the foot of Superior street hill, where she was launched into the river amid the cheers of the assembled crowd.
This was not the first of Cleveland ship-building. About the year 1808, Major Carter built the Zephyr, used in bringing goods, salt, &c., from Buffalo. After good service she was laid up in a creek, a little below Black Rock, where she was found by the British during the war and burned. In 1810, the firm of Bixby & Murray built the Ohio, an important craft of somewhere about sixty tons burden, the ship-yard being lower down the river than the point from which Johnson's craft was subsequently launched. Towards the close of the war she was laid up at Buffalo, when the Government purchased her, cut her down, and converted her into a pilot boat.
Whilst Johnson was building his vessel another was under construction on the flats near the present location of the works of J. G. Hussey & Co. This craft, the Lady of the Lake, about thirty tons, was built by Mr. Gaylord, brother of the late Mrs. Leonard Case, and was sailed by Captain Stowe, between Detroit and Buffalo.
Johnson was now literally embarked on a sea of success. His little ship was in immediate requisition for army purposes. Cargoes of army stores were transported between Buffalo and Detroit. Two loads of soldiers were taken from Buffalo to the command of Major Camp, at Detroit, and on one of the return voyages the guns left by Harrison at Maumee were taken to Erie. The absconding of a quarter-master with the funds in his possession, among other sums three hundred dollars belonging to Johnson, was a serious drawback in the Summer's operations.
In the Spring of 1815, he recommenced carrying stores to Malden, reaching there on his first trip March 20th, and on this voyage Irad Kelley was a passenger. His second trip was made to Detroit. When passing Malden he was hailed from the fort, but as he paid no attention, Major Putoff fired a shot to make the vessel heave-to and leave the mail. The shot passed through the foresail, but was not heeded. A second shot was fired and then Johnson considered it prudent to heave-to and go ashore. He was sternly questioned as to his inattention to the first orders to heave to, and replied that being a young sailor he did not understand how to heave-to. The officer told him to bring the mail ashore, but was met with a refusal, it being contrary to instructions. Johnson started back to his craft and was followed by a party of men from the fort, who manned a boat and gave chase. Johnson, on boarding his vessel, spread sail, and being favored with a good breeze, drew away from his pursuers and reached Detroit, where he placed the mail in the post-office.
During the early part of the war, whilst Johnson was building his vessel and in other ways kept busy, he was chosen coroner of Cuyahoga, being the first to hold that office in the county. The sparseness of the population rendered his duties light, the only inquest during his term of office being over the body of an old man frozen to death in Euclid.
Samuel Baldwin was the first sheriff of the county, and Johnson was his first deputy. His first experience in office was noticeable. Major Jessup, in command of the troops, had brought to Cleveland from Pittsburgh a Mr. Robins, who built from thirty to forty flat bottomed boats, or batteaux, to be used in the transportation of the troops. The Major ran short of funds and left a balance unpaid in the cost of construction. Robins brought suit, and the Major, thinking the deputy sheriff probably had some unpleasant business for him, studiously avoided an interview with Johnson, and whenever they met by chance, pulled out his pistols and warned Johnson to keep his distance. It so happened, however, that no legal documents had been put in his hands for execution, so that the Major was alarmed without cause.
