Here I Am as You Diskiver (1860)-Blackface minstrel tune conflating plantation slavery, the "Indian Nation" (& associated issues of Removal), & antebellum militarism in public space:
Picket Guard (Beers & Hewitt, 1861)-"His musket falls slack, his face dark and grim,
Grows gentle with memories tender,
As he mutters a prayer for the children asleep--
For their mother--may Heaven defend her."
