Explosion of shell — there persons killed and four wounded.
--Between 12 and 1 o'clock yesterday, as some negroes were engaged in unloading a lot of condemned shell which had been sent to the "battery," on the canal, near the pump-house, one of them exploded, and communicating with a pile of others, caused about twenty-five or thirty of them likewise to explode.
Three negroes were killed outright and two others were severely wounded.
Mr. Nicholas Ingersoll
, the foreman of the place, was also mortally wounded.
He had both of his legs broken and mangled, his head and face badly cut and bruised, and a piece of shell was driven into the lower part of his stomach.
A Confederate lieutenant whose name we could not learn, was wounded by a fragment of shell while waiting to take a boat to Belle Isle
, some five or six hundred yards off.
