Here is another:
Boston Herald, US. 23 June, 1862
Second Master Heath, 3d Master Kinzie, 4th Master Seaville, Master’s Mate H.P. Browne, Paymaster, Chief Engineer John Cox and Assistant Engineers John McAfee and Hollingsworth, were killed. Pilot Chas Young, was severely scalded and reported since dead. Surgeons Jones and Carpenter Manning were slightly scalded. From 18 to 100 of our Sailors have already been buried and over 20 are missing.

It appears that the sailors killed outright or died soon after were buried in St. Charles. Years age I saw some headstones at the Memphis National Cemetery marked USS Mound City, but with no names. I wonder if the St. Charles burials were moved to Memphis after the War?
