The President's Thanks to the Forces That Captured Fort Henry and Roanoke Island.

WASHINGTON CITY, D.C., February 15, 1862.

The President, Commander in Chief of the Army and Navy, returns thanks to Brigadier-General Burnside and Flag-Officer Goldsborough, and to Brigadier-General Grant and Flag-Officer Foote, and the land and naval forces under their respective commands, for their gallant achievements in the capture of Fort Henry and at Roanoke Island. While it will be no ordinary pleasure for him to acknowledge and reward in a becoming manner the valor of the living, he also recognizes his duty to pay fitting honor to the memory of the gallant dead. The charge at Roanoke Island, like the bayonet charge at Mill Springs, proves that the close grapple and sharp steel of loyal and patriotic soldiers must always put rebels and traitors to flight.

The late achievements of the Navy show that the flag of the Union, once borne in proud glory around the world by naval heroes, will soon again float over every rebel city and stronghold, and that it shall forever be honored and respected as the emblem of liberty and union in every land and upon every sea.

By order of the President:

EDWIN M. STANTON,
Secretary of War.

GIDEON WELLES,
Secretary of the Navy.

WAR DEPARTMENT,
Washington City, D.C., February 17, 1862.

Brigadier-General F.W. LANDER:

The President directs me to say that he has observed with pleasure the activity and enterprise manifested by yourself and the officers and soldiers of your command. You have shown how much may be done in the worst weather and worst roads by a spirited officer at the head of a small force of brave men, unwilling to waste life in camp when the enemies of their country are within reach. Your brilliant success is a happy presage of what may be expected when the Army of the Potomac shall be led to the field by their gallant general.
