quoting from the poem When war against
Mexico was declared in May 1846, O'Hara left Washington, D.C. to return to his native Kentucky in order to enlist. Within a month, he was appointed Captain of the Kentucky Volunteers, and served as their assistant
quartermaster. Before he returned to Kentucky in 1847, he was made a
brevet major. After hearing of the severe losses that the 2nd Kentucky Infantry and Kentucky cavalry suffered from the
Battle of Buena Vista, O'Hara wrote "Bivouac of the Dead" in dedication of the fallen troops. When many of the fallen Kentuckians were buried in
Frankfort Cemetery on July 20, 1847, future congressman and U.S. Vice President
John C. Breckinridge spoke for an hour at the event. Whether or not O'Hara spoke "Bivouac of the Dead" is disputed, but it is commonly believed that he did. It is agreed he spoke the poem in 1850 at the same cemetery, for the interment of
William T. Barry and General
Charles Scott. "Bivouac of the Dead" would later be called "a worthy contribution to American Literature". It was first published in the
Frankfort Yeoman in 1850. However, modern historians have also claimed it was not written until 1851, after
Narciso López's failed attempt to remove
Cuba from
Spanish control. O'Hara was known to change the lyrics to "Bivouac of the Dead". Alternations included removing mentions of specific places, and removing various stanzas. In 1858 the
Mobile Register published what is believed to be the original version, with the
Louisville Courier publishing the original with an introduction stating it was the version spoken at the 1847 ceremony, reflecting the changes in the poem. In 1900
The New York Times devoted an article decrying all the alterations to the poem, and stressed returning to the original version. When O'Hara was reinterred at Frankfort Cemetery, a friend used "Bivouac of the Dead" as the eulogy. ==Poem usage after O'Hara==
