l3-inch mortars weighing IL 900 pounds, Wcro
several times sunk and nearly loet. road more
than mile long was built OF fascines over ground
not otherwise passable.
Eleven batteries, mounting in all 80 gnns, were
thus slowly and painfully constructed. lhoy "eie
all earthworks, revetted with sods, fascnes' OF
hurdles having parapets not less than eight feet ID
hight. with traverses between the guns, deep and
narrow embrasures, splnter-proofs for all tne ao.
vanced works. capable Of holding the two reheis Oh
punners off duty, and one two service magazines
in each battery. A stone magazine was built near
the lighthouse, with q receiving capacity OF S,oVo
barrels Of powder. 1t was intended that the bat
teries should open with supply Of ammunition ior
nine days uninterrupted fire, but on the 9Th OF April
when thew were ready, not more than half the de-
sred quantity of shot and shell had been landed on
Tybee Island. The number and character OF the
guns in each battery appear the legend of the plan
herewith sent, which is Photographic copy OF the
original drawn by Gen. Gilmore. This plan, and
the orders which append in full, comprise and will
explain many details which are here omitted. The
distance of the batteries from the fort they were de-
signed to reduce is especially to be noted. No prac.
ticable ground lies nearer but the nearest OF these
works is far beyond the limit heretofore supposed
possible for preaching.
Much the largest part Of the heavy and exhaustng
work Of landing the ordnance, transporting 1t, and
throwing lp the earthworks, was done by the 9TH
Connecticut Volunteers, Col. A. II. Terry. Two
companies Of the Volunteer Engineers, COL Serrell,
under Lieut. Col. Hall, were also effectively en-
ployed; and l am told that the services Of Lieut..
Brooks, in command of Company A, were especially
valuable. The 46th New-York, Col. Rosa, was en-
camped on the island, and did some part Of the work
on the trenches. Three companies Of the Sd Rhode
Island were sent down from Port Royal artlerists
The 9Th Michigan, Col. Feoton, the 10Th Pennsylya-
nia Lieut.. Col. Wallace, and five companies Of the
9th Maine, Col. Rust, arrived on the island before
the bombsrdment, 10 prevent any possible attempt
TO relieve the fort. Seven Of the eleven batteries
were served by the who worked in the trenches.
They were entirely without experience ss artiller-
lists, and were instructed in their new duties for q
few days before the bombardment began by Lient.
Porter, Chief of Ordnance and Lieut. Wilson, Chief
Topograpical Engineer, on Gen. Gillmores staff
Tie services of Lieut. Porter throughout the whole
period of the preparation cannot be estimated too
highly. His professional skill and unweared energy
gave TO Gen. Gilmore the most effective cooperation
not only in the ordnance work but engineer and
arterist, and in the numerous experiments ana ex-
pedents necessary in the execution Of plan without
precedent or authority.
Most Of the assignments 10 the batteries will be
found in special order No. 3d. but some changes were
made during the bombardment. The guns in Bat
terry Sigc were so observed at first that the compa,
nies OF the 10th New-York originally detailed were
ordered away, and the battery placed in charge
A oFS Stka
ence on Gen. Hunters staff, an old artillery officer,
and two companies Of the 9Th Maine, under Capt
Macarthur, were assigned to his command. Under
Capt. Turner the guns were effectively served, and
when part Of the battery was aiterward assigned
TO Commodore Rodgers Of the Wabash, Capt. Turn
ers superinteDdence extended over Battery
Mcclellan. Lents. Wilson and Porter Of Gen. Gill
more's staff had aso supervisory charge over Bat
teries Scott and Tot,eu. Capt. Pelouze, acting In
spector-GeDent, Gen. Hunters stsH 10 whom
batteries Lincoln and Lyon were assigned worked
mos, zeslously throughout remountng under fire his
lO-inch columbiads which were upset. owing TO some
defect in the carriages. The guns in Fort Scott, sso
disabled the first day, were replaced by Lieut.
Porter.
At Gen. Hunters request, detachment OF hum
dred saore, under Lieut. Irwin, was sent from the
Wabash By Flag Officer Dupont 10 report 10 Com
mander c. X. p. Rodgers Of that ship, who was al
ready on the island. On the morning Of the second
day Battery Sgel, with the exception of two guns,
was assigned TO Commander Rodgers and that very
able officer and Lieut.. Irwin, with the trained gun
ners of the Wabash did most valuable and effective
service.
The active direction and command Of the forces in
the trenches remained with Gen. Gilmore during
the bombardment. Major-Gen. Hunter was present
as commander Of the Department, and Brighten
Benham as commander Of the District. The latter
also relieved Gen. Gilmore during Thursday night
and had general direction of all the forces both on
Tybee and on the opposite shore, under Gen. Viele.
That officer was ordered 10 plant battery Of NOR
