The ten days ensuing will be forever memorable in the annals of the city of Cincinnati. The cheerful alacrity with which the people rose _en masse_ to swell the ranks and crowd into the trenches was a sight worth seeing, and being seen could not readily be forgotten. Here were the representatives of all nations and classes. The sturdy German, the lithe and gay-hearted Irishman, went shoulder to shoulder in defence of their adopted country. The man of money, the man of law, the merchant, the artist, and the artisan swelled the lines hastening to the scene of action, armed either with musket, pick, or spade. Added to these was seen Dickson's long and dusky brigade of colored men, cheerfully wending their way to labor on the fortifications, evidently holding it their especial right to put whatever impediments they could in the northward path of those whom they considered their own peculiar foe. But the pleasantest and most picturesque sight of those remarkable days was the almost endless stream of sturdy men who rushed to the rescue from the rural districts of the State. These were known as the "Squirrel-Hunters." They came in files numbering thousands upon thousands, in all kinds of costumes, and armed with all kinds of fire-arms, but chiefly the deadly rifle, which they knew so well bow to use. Old men, middle-aged men, young men, and often mere boys, like the "minute-men" of the old Revolution, they left the plough in the furrow, the flail on the half-threshed sheaves, the unfinished iron upon the anvil,--in short, dropped all their peculiar avocations, and with their leathern pouches full of bullets and their ox-horns full of powder, poured into the city by every highway and by-way in such numbers that it seemed as if the whole State of Ohio were peopled only with hunters, and that the spirit of Daniel Boone stood upon the hills opposite the town beckoning them into Kentucky. The pontoon-bridge, which had been begun and completed between sundown and sundown, groaned day and night with the perpetual stream of life all setting southward. In three days there were ten miles of intrenchments lining the hills, making a semicircle from the river above the city to the banks of the river below; and these were thickly manned from end to end, and made terrible to the astonished enemy by black and frowning cannon. General Heath, with his twenty thousand Rebel veterans, flushed with their late success at Richmond, drew up before these formidable preparations, and deemed it prudent to take the matter into serious consideration before making the attack. Our men were eagerly awaiting their approach, thousands in rifle-pits and tens of thousands along the whole line of the fortifications, while our scouts and pickets were skirmishing with their outposts in the plains in front. Should the foe make a sudden dash and carry any point of our lines, it was thought by some that nothing would prevent them from entering Cincinnati.
