_Sandusky_.--All quiet at Sandusky; the army has fallen back into the city, and large reserves are still massed behind. _Editorial Comment_.--The battle of Grierson is a distinct success; the enemy, with a heavy loss, have been beaten back to their own side. As to the vital engagement on the Sandusky and the heavy fighting before Yolo, it is plain that we must wait for further news of both. In neither case has any decided advantage crowned our arms, and if we are to judge by the expressions of the commander-in-chief to our Sandusky correspondent, the course of the former still leaves room for the most serious apprehensions. General Potty, we are glad to assure our readers, will be once more in the saddle before many days. It is an odd coincidence that all the principal commanders in the battle of Grierson were at one period or another of the day carried to the rear; and that none of the three is seriously hurt. Green and Lafayette were shot down, it appears, within a few moments of each other. It was reported that they had been having high words as to the reckless advance over the Sandusky, each charging the blame upon the other; but it seems certain that the fault was Lafayette's, who was in chief command, and was present in Grierson itself at the time of the fatal manoeuvre. The result would have been crushing, had not General Potty been left for some hours utterly without ammunition; Commissary Scuttlebutt is loudly blamed. To-morrow's news is everywhere awaited with an eagerness approaching to agony. 15th. _Scarlet_.--Late last night, orders reached General Pipes to fall back on this place, where his reserves were diverted to support Piffle, hard-pressed on the Sandusky. This morning the manoeuvre was effected in good order, the enemy following us through Grierson and capturing one hundred prisoners. The battle was resumed on the Sandusky with the same fury; and it is still raging as I write. The enemy's Army of the Centre is commanded, as we learn from stragglers, by General Napoleon; they boast of large supports arriving, both from Savannah and Tahema directions. The slaughter is something appalling; the whole of Potty's infantry corps has marched to support Piffle; and as we have now no more men within a day's ride, it is feared the enemy may yet manage to carry Garrard and command the line of the river.
