It was a part of the Union forces gathered at Grand Junction, TN for the advance on Vicksburg, MS. In the latter part of January the Sixteenth embarked at Memphis and moved down the river to Lake Providence, LA, where a landing was made February 1, 1863. From that place and Red Bone Church, MS, the Sixteenth was engaged in guard duty and minor expeditions until February 1864, when it returned to Vicksburg.
