To General G. B. Mcclellan.

Executive Mansion, Washington, March 31, 1862

MAJOR-GENERAL McCLELLAN.

MY DEAR SIR:-This morning I felt constrained to order Blenker's division to Fremont, and I write this to assure you I did so with great pain, understanding that you would wish it otherwise. If you could know the full pressure of the case, I am confident that you would justify it, even beyond a mere acknowledgment that the commander-in-chief may order what he pleases.

Yours very truly,
A. LINCOLN.
