Hanapepe massacre

The Hanapēpē Massacre (also called the Battle of Hanapēpē since both belligerents were armed) happened on September 9, 1924. Toward the end of a long-lasting strike of Filipino sugar workers on Kauaʻi, Hawaiʻi, local police shot dead nine strikers and fatally wounded seven, strikers shot and stabbed three sheriffs to death and fatally wounded one; a total of 20 people died. As reprehensible as it may appear in retrospect, the incident did not arouse contemporary public censure nor bring into question the legitimacy of the coercive agents or their actions. The massacre brought an end to armed protests in Hawaii.
