Minister of Foreign Affairs Robert Crichton Wyllie advocated for a declaration of neutrality, following the one made by the previous king Kamehameha III during the Crimean War in 1854, while King Kamehameha IV and Minister of Finance David L. Gregg feared the diplomatic repercussions of recognizing the belligerent status of the Confederate States of America and were initially reluctant to risk displeasing the United States with any form of recognition of the Confederacy.
[4] A few months before the neutrality proclamation, an American expatriate and businessman, Captain Thomas Spencer, personally funded and drilled a company of infantry composed mostly of Native Hawaiians from Hilo on the island of Hawaii.
However, to avert diplomatic controversy and in defense of the Hawaii's neutrality, King Kamehameha IV and Foreign Minister Wyllie officially denied permission for the men to go as a unit.
[9] Many Hawaiians sympathized with the Union because of Hawaii's ties to New England through its missionaries and the whaling industries, and the ideological opposition of many to the institution of slavery, which the Constitution of 1852 had specifically officially outlawed in the Kingdom.
[7][12] Notable volunteers from Hawaii include: Henry Hoʻolulu Pitman, Samuel C. Armstrong, Nathaniel Bright Emerson, James Wood Bush, Prince Romerson, and J. R.
The exact number still remains unclear because many Hawaiians enlisted and served under Anglicized names and little is known about them due to the lack of detailed records.
[19][20][21] In 2013, Todd Ocvirk, Nanette Napoleon, Justin Vance, Anita Manning and others began the process of creating a historical documentary about the individual experiences and stories of Hawaii-born soldiers and sailors of the American Civil War from both the Union and the Confederacy.
