July 22.–Just received news of a dreadful defeat at Manassas, or beyond Centreville. General McDowell’s column pushed on after some successes, were met apparently by fresh troops, checked, driven back, utterly routed! What a calamity! Will not the secession fever sweep over the border States, driving out Kentucky, Missouri, (Baltimore) Maryland, etc., etc.? Is not Washington in danger? I have feared a too hasty pushing on of McDowell’s column into ground where the Rebels have camped and scouted and entrenched themselves for months. My brother-in-law, as surgeon, is with the Second Ohio Regiment in advance, and is doubtless among those in the worst position. But private anxieties are all swallowed up in the general public calamity. God grant that it is exaggerated!
Our regiments are now likely, I think, to be speedily needed at Washington or elsewhere. I am ready to do my duty, promptly and cheerfully. Would that I had the military knowledge and experience which one ought to have to be useful in my position! I will do my best, my utmost in all ways to promote the efficiency of our regiment. It is henceforth a serious business.
