Message to the Senate Nominating Commander D. D. Porter to be a Rear-Admiral in the Navy
To the Senate of the United States:
Congress, on my recommendation, passed a resolution, approved 7th February, 1863, tendering its thanks to Commander D. D. Porter "for the bravery and skill displayed in the attack on the post of Arkansas on the 10th January, 1863," and in consideration of those services, together with his efficient labors and vigilance subsequently displayed in thwarting the efforts of the rebels to obstruct the Mississippi and its tributaries and the important part rendered by the squadron under his command, which led to the surrender of Vicksburg.
I do therefore, in conformity to the seventh section of the act approved 16th July, 1862, nominate Commander D. D. Porter to be a rear-admiral in the Navy on the active list from the 4th July, 1863, to fill an existing vacancy.
