General,—Should the enemy's ironclads enter the harbor, the
Commanding General thinks it probable they will endeavor to take the
Fort Johnson lines facing towards
Morris Island in flank and reverse, to favor an infantry attack upon Battery Simkins, and, possibly at the same time, make a similar front attack from
Fort Johnson to the
Martello Tower.
It becomes important, then, to guard against the first by traverses wherever required, and against the second by a line of rifle-pits or infantry parapets, connecting the batteries near the
Martello Tower with the one at
Fort Johnson.
The
Commanding General, therefore, desires you, assisted by
Colonel Harris, to make a proper examination to determine whether these rifle-pits should be prolonged to the creek below Battery
Wampler, or turned back near the
Martello Tower towards the marshes facing
Morris Island, wherever the ground is most favorable for such a defensive line; or whether the detached redoubts, ordered some time ago, should be at once commenced, suspending meanwhile further labor on the “new lines,” which are now deemed quite defensible.
Respectfully, your obedient servant,
