HEADQUARTERS DEPARTMENT OF VIRGINIA,
Fort Monroe, Va., March 29, 1863.

Honorable G. V. FOX, Assistant Secretary of the Navy.

SIR: I have the honor to inform you that by the direction of the Secretary of War exchanges of officers will now be resumed. There are many naval officers now in confinement in the South. The Confederate authorities refuse to release them unless the captures on the sea which were declared exchanged by General Orders, No. 11, current series, and for which they have given equivalents are released. This rule they also declare their intention to apply to future captures. They ask that the rule of reciprocity be carried out in captures on the sea as on the land. You know how carefully I have endeavored to carry out the wishes of your Department and from a sense of courtesy have uniformly given to it in the arrangement of my declarations of exchange preference over our own branch of the service. I respectfully, your await instructions from your.

I am, very respectfully, your obedient servant,
