Approximately 30 Confederate hospital stewards were left behind at Gettysburg to tend to their wounded. William Fares Smith of the 28th Virginia was left with the wounded at Williamsport, Maryland on the retreat - he received an M.D. from the University of Pennsylvania's Medical Department in 1861.
David Mitchell Currie, hospital steward of the 6th North Carolina, received his M.D. from the same institution in 1850. Junius McQuide Witherspoon, with the 48th Mississippi, received his baccalaureate from the University of Alabama in 1854.
Royal Louis Cleaves, a hospital steward "second class" with the 16th Maine, received his M.D. after the war, in 1869, from Harvard College. Henry Hastings Hunt, with the 5th Maine Battery, obtained his baccalaureate from Bowdoin College in 1862.
Field hospital staff were known to turn away men from units in other commands, or if they were present, gave them a lower priority. At Spotsylvania, Avery Harris of the 143rd Pennsylvania took a wounded comrade to where a red hospital flag was displayed. Upon learning the regiment, the surgeon and assistant surgeon told him to take him to his own hospital; "don't want him here." But "the hospital steward, a kind-hearted man, said to leave the man with him and he would take care of him."
