The annals of naval warfare record few enterprises which exhibit more strikingly than this of Lieutenant Glassell the highest qualities of a sea officer.

At this time there were sixty officers and men on torpedo duty at Charleston alone.

The most remarkable career in all torpedo history was that of a little boat built in Mobile Bay, and operated upon the fleet off Charleston. She was the pioneer of all submarine torpedo boats, as she was the first to achieve success.

She was built in 1863–4 at Mobile by Mr. Horace L. Hunley, at his own expense.
