W. H. Gardner to G. Wright, U. S. Army, March 15, 1862

Brig. Gen. G. WRIGHT, U. S. Army, Commanding Department of the Pacific, San Francisco, Cal.: GENERAL: Your letter of the 12th instant is received, informing me that a reconnaissance has been made by the chief engineer of the army on this coast, and a plan of defensive works submitted to guard the approaches to the city of San Francisco either by land or water. In answer I have to say that it will afford me great pleasure to contribute all the means at my command to assist in fortifying such batteries as you may deem proper to construct. I inclose herewith a list of such ordnance as we have on Mare Island. These guns have none other than the common ship carriage, and it may be necessary to construct carriages to suit them in the batteries.

I have the honor to be, respectfully, your obedient servant,
