Greetings - my first official post on this forum

My great-great grandfather Henry Emil Otto Wapler served aboard the Diana in 1863. In September of that year at Sunnyside Landing (Greensville Bridge), according to his pension records, he was forced to stand guard under the heavy guns on the Diana during a severe cannonading for about two hours. He suffered total hearing loss which lasted for a month at which time he had partial recovery of his hearing in his left ear. He claimed the experience also made worse a vericose vein condition in his left leg which caused him much trouble later in life. In any event, my records on my relative also include a formal War Department letter from May 14, 1886 responding to an inquiry about his reported experience aboard the Diana:
<snip>..."Regimental Letter book shows Steamer Diana was at Greenville Miss., June 8 1864. Morning reports of CoC above organization, June 8 to 14, 1864, show above named steamer was at Greenville Miss.... Morning reports of Co Diana not on file."
Reading from this, it's hard to tell. I believe they were saying that they'd confirmed from 1864 log book entries that the Diana had been in Greenville (in confirmation of my relatives disability claim). However, it also could be reporting the ship was in Greenville on the dates June 8-14, 1864, which seems to be in conflict with reports that the ship had been destroyed by that time. Though I wonder at the relevance of the latter interpretation in light of my relatives claim situation.
In any event, Otto was a colorful character by any measure. He was a Prussian immigrant who got directly on a train out west to Illinois immediately after getting off the boat in New York in 1858. A year or two before joining up with the Union in Indiana, he'd joined a wagon train out to Colorado to chase gold in Golden, Co. with his buddy. During the experience, he talks of smoking the peace pipe with local Indians, but warns the reader that he didn't trust them as they were wont to thieve as anything. He ran around the hills in that area for a season, getting stuck in a river crossing with his ox team, and then finally made it back to Indiana after empty pockets and his fill of adventure.
After the war, he settled down in Kansas to a career as a cabinet maker and had a bevy of daughters (his 'Jayhawks' he called them fondly) - one of which of course was my great-grandmother
