Perhaps Danels eventually succumbed to his illness, whatever it was, and was not wounded. There have been other errors shown in official sources, as Les Rolston and I recently found out. Les recently enquired about a soldier aboard the COMMODORE BARNEY who was awarded the MOH, and we found out, through the Naval Official Records, that this soldier was not on the COMMODORE BARNEY, but aboard the COMMODORE PERRY. Yet all recent publications on those awarded the MOH indicate that this soldier, Burbank, was aboard the BARNEY.
Callahan's "List of Officers of the U.S. Navy" volume, originally published in 1901, indicates that Danels "died of wounds, 23 March, 1865." Perhaps this was in error and perhaps his illness, as mentioned in several reports, dated in January, 1865, was the cause of his death. The Navy file on Danels would almost certainly show this data, as would, perhaps, the deck log of the USS VANDERBILT, which returned north (to New York, if I remember correctly) after the Fort Fisher campaign.
