Kamehameha landed a huge
invasion fleet on Oahu in 1795 and skirmished with the Oahu forces as he
advanced across the plain where Honolulu now stands. The Oahu army made a stand
but was driven up Nu'uanu valley in hard fighting. The upper valley terminates
at the brink of a thousand-foot cliff (pali), and here those of the Oahu army
who found no escape along the ridges or down a narrow cliffside trail were
driven over the precipice. Both sides used firearms as well as traditional
weapons, and included a foreigners in their ranks. In the narrow upper valley
Kamehameha's well-disciplined phalanx, a tight formation carrying long lances,
could not be stopped.
