SAN SIMON, ARIZ. TER., July 18, 1862.

Lieutenant Colonel J. R. WEST,

Tucson, Ariz. Ter.:

COLONEL: I have the honor to inform you in the late fight with the Indians at Apache Pass both of my stock-trails to my howitzers were broken or rendered almost useless on account of the great elevation required. One I think would not have broken were it not for a flaw in the iron strap around the axle-tree. Having fixed on a plan which I think will render the pieces fit for any service required of them, I send with Captain Roberts' permission one of my gunners with a trail and axle-tree. The gunner understands my plans fully, and with your sanction will carry them out. The plan is to raise the gun from the axles, so as to give more wood and strength to the stocks, and then strenthen them with iron plates. If you favor my plan I should like to have made a new trail and axle for the piece which remains here. I am in want of a few bolts, of which Monihon (the gunner) has a list. I also want some ammunition, having fired in the two days forty rounds, leaving me but sixty-five rounds. I would ask if it is possible for me to get pistols and sabers for my men, as it is useless to go in action
