The 1 May date has no support
No reliable evidence fixes this battle to 1 May. Modern references variously place it in late April or May 1795, and the surviving traditions and early written accounts are varied and sometimes contradictory.
What the sources agree on is the approach: Kamehameha landed at Waikīkī, waited several days, then advanced inland — not westward — against Kalanikūpule's defensive position in Nuʻuanu Valley on Oʻahu.
Because the accounts conflict, precise tactical reconstructions of the fighting have to be qualified rather than asserted.
Ten thousand men and twelve cannon
Kamehameha's force is estimated at around 10,000 men, with 12 cannon commanded by Europeans; John Young and Isaac Davis are associated with his use of European ships, firearms and artillery. Scholarship warns against reducing the victory to guns and foreign advisers alone.
The numerical and artillery advantages gradually broke the defenders, who fell back into the narrowing, forested upper valley.
Kaʻiana, who had left Kamehameha's fleet during the approach and joined Kalanikūpule, was killed — though accounts disagree about where and how he died.
What the pali story exaggerates
Some defenders got away along the valley slopes, the mountain ridges or the windward trail. Others were trapped against Nuʻuanu Pali — put at 304 metres in the scholarly reconstruction — and killed on or below the cliff.
Near-contemporary reports give defending losses of 300 in one account and at least 500 in another. The same study treats even a claim of 400 driven over the pali as probably exaggerated, so the familiar figure of more than 700 is a legendary estimate rather than a count.
Kalanikūpule escaped into the Koʻolau Mountains and was captured and sacrificed only after hiding for several months; Kauaʻi and Niʻihau stayed outside Kamehameha's authority until Kaumualiʻi accepted it in 1810.

Date disputed. Sources disagree; the research places it at ~1795-05.
What the sources leave uncertain
- No reliable evidence supports the exact date 1 May. Modern references variously place the battle in late April or May 1795.
- Accounts differ over Kaʻiana’s manner and location of death, whether Kalanikūpule was wounded, and how many defenders died or went over the pali.
- Surviving traditions and early written accounts are varied and sometimes contradictory; precise tactical reconstructions should therefore be qualified.
