'The defence was gallantly kept up by the battery of San Miguel, under Sub-Lieutenant of Artillery Don Josef Marrero; by the Castle of San Pedro, [Footnote: The San Pedro battery dated from 1797. It defended the southern town with six embrasures and three guns _en barbette_. For many years huge mortars and old guns lay outside this work.] under the Captain of Artillery Don Francisco Tolosa; by the Provisional Battery de los Melones, [Footnote: Now destroyed. It was, I have said, near the new casemates north of the town.] under the Sergeant of Militia Juan Evangelista; by the Mole-battery, under Lieutenant of the Royal Corps of Artillery Don Joaquim Ruiz and Sub-Lieutenant of Militia Don Francisco Dugi; by the Castle of San Cristobal, under the Captain of the Royal Regiment of Artillery and Brigade-Major Don Antonio Eduardo, who commanded the central and right batteries, and Lieutenant of Militia Artillery Don Francisco Grandi, to whom were entrusted the defences on our left; by the battery of La Concepcion, [Footnote: Where the Custom House now is, in the middle of the town.] under Captain of the Royal Regiment of Artillery Don Clemente Falcon; and by that of San Telmo, [Footnote: Near the dirty little square south of the Custom House. The word is thus written throughout the Canary Islands; in Italy, Sant' Elmo.] under the Captain of Militia Artillery Don Sebastian Yanez. 'The rest of our line did not fire, because the enemy's boats had not passed the Barranco, or stony watercourse, which divides the southern from the northern town. In the Castle of San Juan, [Footnote: It is the southernmost work, afterwards used as a powder-magazine. To the south of the town are also the Bateria de la Rosa, near the coal-sheds, and the Santa Isabel work. The latter had 22 fine brass guns, each of 13 centimètres, made at Seville, once a famous manufactory.] however, Captain Don Diego Fernandez Calderia trained four guns to bear upon the beach, which was protected by the Laguna militia regiment, under Lieutenant-Colonel Juan de Castro.
