To General D. Hunter.

(Private.) Executive Mansion, Washington, D. C April 1, 1863.

MAJOR-GENERAL HUNTER.

MY DEAR SIR:—I am glad to see the accounts of your colored force at Jacksonville, Florida. I see the enemy are driving at them fiercely, as is to be expected. It is important to the enemy that such a force shall not take shape and grow and thrive in the South, and in precisely the same proportion it is important to us that it shall. Hence the utmost caution and vigilance is necessary on our part. The enemy will make extra efforts to destroy them, and we should do the same to preserve and increase them.

Yours truly,

A. LINCOLN.
