A lull then occurred for another attempt of the engineers to finish the bridges, but again they failed, owing to the increased severity of the rebel fire. At nine another general cannonade was opened upon the rebel cover from over a hundred light and heavy guns. The roar of the discharges, the whizzing of the missiles, the bursting of the shells, and the crashing as they struck the buildings, combined in a deafening and yet inspiring war concert. At ten, our fire ceased, when the engineers once more endeavored to add pontoons to those already in place, only to be again driven back. Our batteries repeated their performance, pouring shot and shell upon the buildings from which the rebels fired. At eleven, the fog had lifted sufficiently to make the houses and streets distinguishable, thus giving surer aim to our artillerists. To a column of rebel infantry seen moving down a street they at once gave attention, making it disappear. The whole forenoon was thus spent in futile efforts for the completion of the upper bridges. It became evident, too, that every new attempt made it harder for the engineer officers to get their men to expose themselves. The latter finally refused to obey orders, or ran away from the pontoons to shelter as soon as the hostile bullets whistled around them. Irritated at this successful defiance of us by a small rebel force, General Burnside, shortly after noon, ordered a general bombardment of the town at large. Some one hundred and fifty guns were accordingly turned upon it, causing, as it seemed to me, twice as furious a roaring as before. Several buildings were soon seen to burn. This terrific cannonade was kept up for nearly two hours, when it was stopped for a further effort to finish the bridges.
At the suggestion of the chief of artillery, General Hunt, it was decided to try and rush troops across the river in bridge boats, to attack and drive away the enemy. This dangerous duty naturally devolved upon, and was accepted with alacrity by, the regiments serving as supports to the several bridge trains. At the upper bridge, the Seventh Michigan was to cross, while the Nineteenth Massachu-
