luck, considering the severe fire that this heroic little band were exposed to. The loss of the enemy we have not positively ascertained: we hear of thirteen killed, with certainty, and general report says thirty-five; wounded not known. Of the total loss of the enemy in their attack upon the cuartel, I cannot speak with certainty; we have found several graves, and know of a number wounded, one of whom we have in the cuartel a prisoner. I suppose their total loss to be not far from fifteen killed, and many wounded; I am sure it could not be less than this. Our own total loss was three killed and four slightly wounded. After the death of Passed Midshipman McLanahan, there remained but one officer to my assistance, Passed Midshipman George A. Stevens, to whom, for his coolness and indefatigable zeal at a time when so much devolved upon him, I am most happy to accord the highest credit; and at the same time I must honorably mention the conduct of a volunteer, Eugene Gillespie, Esq., who, although suffering from illness, never deserted his post, and was with me in the sortie of the 7th. The non-commissioned officers and men went through privation, unceasing watchfulness, and danger, without a murmur. I cannot express too highly my satisfaction in their conduct. Captain Dupont immediately upon his arrival here, becoming aware of our situation as regards provisions, took measures for our supply. The day after the battle of San Vincente he despatched a train, which brought us by hand (the enemy having driven off all the mules and horses) a quantity of stores and articles of which we stood most in need, among the rest, bread, and has since been unceasing in his exertions for our relief. I cannot too earnestly express the obligations which we are under for the prompt and efficient assistance which Captain Dupont, his officers, and crew have rendered us. I am, sir, respectfully, your obedient servant, CHAS. HEYWOOD, _Lieutenant U.S. Navy, com'g., San Jose_. Lieut. Col. HENRY S. BURTON, _U.S. Army, com'g. troops in Lower California_. W. T. SHERMAN, _First Lieutenant 3d Artillery, A.A.A. General_. H. UNITED STATES BARRACKS, _La Paz, California, April 13, 1848_. SIR: I have the honor to acknowledge the receipt of your letter of March 1, 1848, and to report the arrival of the army storeship "Isabella" at this place on the 22d of March, 1848, with Captain Naglee's company (D) New York volunteers, and one hundred and fourteen recruits for the detachment of New York volunteers stationed at this place.
