Note 17 — VIII PALO ALTO, RESACA DE LA PALMA May, 1846

When Taylor set out for Point Isabel, though he described the fort as “in a good state of defense,” one side was still open, and the drawbridge and interior defences had not been begun (66Mansfield to Totten, June 23; diary in Nat. Intelligencer, Sept. 3); and not before the night of the third was the position considered by its defenders even comparatively secure. The fort had six bastion fronts, which made a perimeter of 800 yards, a strongly designed wall of earth 9½ feet high from the natural ground, a parapet 15 feet thick, a ditch about 8 feet deep and from 15 to 22 feet wide, a gate and a drawbridge (mostly from 66Mansfield to Totten, Apr. 23). For about 4 feet from the base the inside of the wall was fortified with a sort of basket work of willow twigs. The magazine was made of pork barrels filled with sand, seven tiers thick and four tiers high, with a timber roof covered with 10 or 12 feet of sand. The fort was a “child of circumstance,” admitted Engineer Mansfield (66supra), and in addition to the faults of position already mentioned, the ground was irregular and the defence was made difficult by the extent of the walls, for as considerable portions were allowed to remain covered with thick chaparral (66Mansfield, supra), its area was evidently too large for the 500 men which it had been intended to cover; but it was after all a strong work, and in comparison with it Mansfield regarded the Mexican forts as “trifling” (66to Totten, May 4). Near the end of April the four 18-pounders were removed from the battery to a bastion of the fort looking toward Matamoras, where they were protected with merlons faced with sand-bags, and so attack as well as defence was provided for; but there were only 150 rounds of ammunition for each of these guns.
