Counter-marching. - The 3d Regiment of United States' Artillery under Col. Mitchell, and Capt. Harris' troop of Lt. Dragoons, which a short time since passed through this village for Niagara, have once more faced to the "right-about," and are now marching (we understand) to Sackets Harbor, for its defense. Maj. Gen. Brown has also passed this for the Harbor.
Accounts from Sackets Harbor, represent the alarm at that place to be very serious in consequence of the naval superiority of the enemy on the Lake, and the small force at the Harbor for its protection.
The cannon, cables, & c. for the new ships on Lake Ontario, are now on their way from Albany to Sackets Harbor, but it is said to be altogether impracticable to proceed with the cannon beyond Utica, until the roads become settled.
