That no farther results were to be hoped for than the arrest of the Federal advance toward Richmond, he endeavors to demonstrate as follows: "A movement upon Washington was out of the question. We could not have carried the intrenchments by assault, and had none of the means to besiege them. Our assault would have been repulsed, and the enemy, then become the victorious party, would have resumed their march to Richmond; but if we had captured the intrenchments, a river, a mile wide, lay between them and Washington, commanded by the guns of a Federal fleet. If we had taken Alexandria, which stands on low and level ground, those guns would have driven us out in a few hours, at the same time killing our friends, the inhabitants. We could not cross the Potomac, and therefore it was impracticable to conquer the hostile capital, or emancipate oppressed Maryland." But these statements, ample, as far as they go, in the vindication of Mr. Davis, only partially tell the story of Manassas. They do not fully describe his real relation to the question, though we are far from imputing to General Johnston an intentional omission. A statement of Mr. Davis' views was not necessarily germane to General Johnston's explanation of his own conduct. His purpose is to establish the reasons which induced him to decline pursuit of the enemy, or rather, which, in his judgment, made pursuit impracticable. Nor is it germane to our purpose to discuss these reasons; to attempt either a demonstration of their fallacy or an argument in their support. They have not been accepted as conclusive either by the public, or by unanimous military judgment.
