Notes:
* Manuel Balbontin, a Mexican artillery officer during the war (La Invasion Americana 1888) does not cover the battle.
* Mexican Artillery batteries usually had 4 guns. Batteries with larger guns had fewer than this. Guns were grouped together by size, i.e. a battery of 4 four pounders ( 4-4 lbs.), or a battery of 3 twelve pounders (3-12 lbs.) A total of 43 guns would indicate about 11 batteries. Col. L. Palacios was killed while commanding artillery. Naval Capt P. Ruiz y Baranda, Naval Lt. F. Fernandez, and Capt. V. Arguelles and Lts. M. Camacho, B. Arnable & J. R. Cobarrubias were all captured commanding artillery. Naval Capt. Godinez and artillery officers Malagon and Olzinger were also present. Battery commanders? Naval Capt. Araujo, above was probably a battery commander also. Or, about ten battery commanders.
