Independence Hill and the Bishop's Palace were the keys to Monterey's western approach. After taking the redoubt on the crest of the hill early on September 22, Gen. Worth's men began to bombard the fortified Bishop's Palace with a 12-pounder howitzer that they had disassembled and dragged up the crest.  This view depicts the view from Independence Hill on the day following the final battle.  At far left in the distance (at the print's border) is the Black Fort or "Citadel", which remained in the hands of the Mexican defenders hampering Taylor's operations on the eastern side of the city.  To the left of the Bishop's Palace, on the plain, are Arista's palace and garden, and beyond them the Santa Catarina River.  Federation Hill appears at far right.
