(10-inch) columbiad, in complete circle in barbette, defended by 200 men. Third. Submarine batteries in the principal channels, at various depths, to be fired by galvanic battery. The moral effect of this is immense upon the enemy, and its practical results sure if well constructed. The same means repeated, if possible, at Fort Pillow and Memphis. Finally, using for the guns on the hills the depression carrigae used at Gibraltar by the British. It is simple, efficient, cheap, and can be built at the rate of five to one columbiad barbette carriage. Let me also suggest to you the importance of a company of sapers and miners to execute and direct the workmen in executing all these works. We can get the material here with proper authority; also a bridge train-say 150 men, with boats, tools, carriages. This is indispensable in Kentucky and Tennessee, and will more than once enable you to surprise the enemy by throwing a bridge on a river, or of saving the army by being enabled to cross a river and destroying your bridge. In two months I can promise to get up such a corps, the men being taken from old soldiers of the French army and formerly belonging to the pontoniers.

I now close this long letter, and remain, yours, very truly,

J. TRUDEAU,

Brigadier-General.
