Ma waena o 1861 a me 1865, ua komo ʻo ʻAmelika Hui Pū ʻIa i kahi hakakā koko i make ai ke ola o nā kānaka he 600,000. ʻO ke Kaua Kivila, e like me ka mea i kapa pinepine ʻia, ua hakakā ʻia ma nā ʻaoʻao he nui: ʻo ka Northern Union e kūʻē i ka Southern Confederacy. ʻOiai ua pau ke kaua me ka lanakila ʻana o ka ʻĀkau a hoʻopau ʻia ka hoʻoluhi ʻana ma ka ʻāina, ʻo ia kekahi o nā hakakā koko loa i ka mōʻaukala ʻAmelika.
ʻO kahi mea nui o kēia kaua weliweli, ua manaʻo ʻia ua komo nā ʻānela i nā manawa he nui e kōkua a hoʻōla i nā koa Union. He nui nā koa i hōʻike i ka ʻike ʻana i nā kukui liʻiliʻi a puni lākou i ko lākou waiho ʻana e make ana i ko lākou ʻeha a i ʻole ma mua o ko lākou ʻeha ʻana. Ua manaʻo kekahi poʻe he kumu hoʻohālike kēia o ka lani komo ʻana i nā hana kanaka.
ʻO "Angel's Glow" ka inoa i hāʻawi ʻia i kēlā ʻano mea kupanaha lani i hana ʻia ma ke kaua ʻo Silo, i ka wā o ke Kaua Kivila. Ua ʻike nā tausani koa i ka ʻālohilohi mai ko lākou mau ʻeha a kōkua iā lākou e hoʻōla. ʻOiai ke ʻano ʻē o ka hihia, hiki ke wehewehe.
ʻO ke kaua o Shiloh (1862), ke koko koko loa o ke Kaua Kivila ʻAmelika, ʻo ia ka hoʻouka kaua ʻana a nā Confederates e kūʻē i ka Union, e hoʻoneʻe iā lākou a haʻalele i ka muliwai Tennessee. Akā ʻo ka huikau o nā pūʻali i hoʻohuli i kēlā wahi i kahi luku i hoʻopau ʻia me ka lanakila o nā pūʻali Union, a me ka make o Dantesque: ʻoi aku ma mua o 3,000 mau koa i luku ʻia a ʻoi aku ma mua o 16,000 i hōʻeha ʻia. ʻAʻole hiki i nā kauka ma nā ʻaoʻao ʻelua ke mālama i kēlā me kēia, a ʻo ka mea ʻoi loa ka lōʻihi o ke kōkua i ʻelua mau lā.
A ma laila, e noho ana i loko o ka lepo, i ka waena o ka pō anuanu a me ka ua i kekahi manawa, ua ʻike kekahi mau koa i ko lākou mau ʻeha e hoʻopuka nei i kahi ʻōuli uliuli ʻōmaʻomaʻo, kahi mea a lākou i ʻike ʻole ai ma mua. I ka wā a lākou i heʻe hope aku ai, ʻo ka poʻe i ʻike i ko lākou ʻeha e ʻūlū ana he ʻoi aku ka nui o ke ola, hoʻōla wikiwiki, a waiho ko lākou mau ʻeha i nā ʻili ʻili. No ka mea a lākou i kapa ai ʻo ka ʻĀnela Aniani.
ʻAʻole i wehewehe ʻia ka moʻolelo a hiki i ka 2001, i ka manawa i hana ai kahi haumāna kula kiʻekiʻe 17 makahiki, ʻo Bill Martin, a me kāna hoaloha ʻo 18 Conaon, ka noiʻi no kā lākou papahana ʻepekema a noi aku i kahi bacteria i kapa ʻia ʻO Photorhabdus luminescens hiki ke kuleana iā Angel's Glow hanana.
Luminescent kēia mau koʻohune a noho wale i ke anuanu a me nā wahi anuanu. Ua hoʻoili ʻia ke kaua ma ka mua o ʻApelila i ka manawa i haʻahaʻa ai ka mahana a pulu ka ʻāina i ka ua. Ua waiho ʻia nā koa hōʻeha i nā mea o ke kūlohelohe a ua loaʻa i ka hypothermia. E hāʻawi kēia i kahi kūpono no P. luminescens e hopu a pepehi aku i nā koʻohune ʻino e hōʻalo ana i nā maʻi hiki ʻole. A ma hope ma ka haukapila, ma lalo o nā ʻano mehana, ua make kēia mau koʻohune, me ka waiho ʻana i ka ʻeha maʻemaʻe loa.
ʻO ka pinepine, ʻo kahi maʻi bacteria i kahi ʻeha hāmama e hoʻolaha i kahi hopena make. Akā he hanana kēia kahi i hana pono ai ka bacteria maikaʻi i ka manawa kūpono i ka mālama ola ʻana. No laila, mahalo paha nā koa ma Silo i kā lākou mau hoa aloha microbial. Akā ʻo wai ka mea i ʻike i ia manawa ua hele mai nā ʻānela i nā nui microscopic? A ʻo Martin lāua ʻo Curtis, ua lanakila lāua i ka hoʻokūkū hui ma ka 2001 Intel International Science and Engineering Fair.
