It was long after midnight when Carleton finished the closing lines of his letter, and then stepped out upon the steamer's guard for a little fresh air. Over on Sumter's walls the signal-light was being waved. The black monitors lay at their anchorage. Ocean, air, and moonbeams were calm and peaceful. From the flag-ship, which the despatch steamer visited, the report was, "The engagement is to be renewed to-morrow afternoon." Nevertheless, the next day, Admiral Du Pont, dissenting from the opinions of his engineers and inspectors, as to a renewal of the attack, moreover finding his own officers differing in their opinions as to the ability of the fleet to reduce Fort Sumter, ordered no advance. The enterprise was, for the present, at least, given up. So Carleton, after another letter on white and black humanity in South Carolina, which showed convincingly the results of slavery, sailed from Hilton Head. Like the war-horse of Hebrew poetry, he smelt the battle afar off, and looked to Virginia. He reached home just in time to hear of the great conflict at Chancellorsville. Rushing to Washington, and gathering up from all sources news of the disaster, he presented to the readers of the _Journal_ a clear and connected story of the battle. During the latter part of May and until the middle of June, the previous weeks having been times of inaction in the military world, Carleton recruited his strength at home. Like a falcon on its perch, he awaited the opportunity to swoop on the quarry. CHAPTER XII. GETTYSBURG: HIGH TIDE AND EBB. When Lee and his army, leaving the front of the Union army and becoming invisible, when President and people, general and chief and privates, Cabinet officers and correspondents, were wondering what had become of the rebel hosts, and when the one question in the North was, "Where is General Lee?" Carleton, divining the state of affairs, took the railway to Harrisburg. Once more he was an observer in the field. His first letter is dated June 16th, and illuminates the darkness like an electric search-light. General Lee, showing statesmanship as well as military ability, had chosen a good time. The Federal army was losing its two years' and nine months' men. Vicksburg was about to fall. Something must be done to counterbalance this certain loss to the Confederates. Paper money in the South was worth but ten per cent. of its face value. Recognition from Europe must be won soon, or the high tide of opportunity would ebb, nevermore to return. Like a great wave coming to its flood, the armed host of the Confederacy was moving to break at Gettysburg and recede.
