Fort Pulaski through the Federal siege.
[Elliott, op.cit.]
Fort Pulaski was considered invincible with its 7-1/2-foot solid brick walls and reinforcing masonry piers. Lee had earlier surveyed the fort's defenses with Colonel Olmstead and determined, "they will make it pretty warm for you here with shells, but they cannot breach your walls at that distance." Wide swampy marshes surrounded the fort on all sides and were infested with native alligators. No attacking ship could safely come within effective range, and land batteries could not be placed closer than Tybee Island, one to two miles away. Beyond , smoothbore guns and mortars had little chance to break through heavy masonry walls. Beyond , they had no chance at all. Prior to the war, the U.S. Chief of Engineers, Colonel

[Lattimore, Ralston B., op.cit.] If there were ever to be a successful siege, it would have to starve the garrison into submission.
Defense in depth
When Federal forces first made a lodgment on Tybee Island, the work on Fort Pulaski was progressing slowly, but Lee's judgment as the district's commanding general was that "the river cannot be forced". Old Fort Jackson had been armed, strengthened and "forms an interior barrier". Savannah's channel had been blocked. In December, Lee reasoned that, since the Federals had sunk a

in the Charleston Harbor, they did not intend to use it. "We must endeavor to be prepared against assaults elsewhere on the Southern coast." To that end, ships were sunk by the Confederates in the water approaches that led behind Fort Pulaski.
Lee brought Commodore
Josiah Tattnall from a James River command and would employ sailors to service at a battery across from Savannah's Fort Jackson. Turning his attention to Fort Pulaski's defenses, Lee anticipated Union moves to establish batteries above the fort. He ordered guns positioned to cover their likely positions were the Federals to get behind Pulaski in a siege attempt.
In January, following Tattnall's three-

attack on seven Federal gunboats on the river, Lee's assessment was that "there is nothing to prevent their reaching the Savannah River, and we have nothing afloat that can contend against them."
Fort Pulaski, a "Third System", scientifically engineered coastal defense fort, still had at least four months' provisions. Now, the primary objective became, "we must endeavor to defend the city." The city's floating dock was sunk as another river obstruction.
In March, Lee passed along War Department orders to begin transferring regiments from Florida to Tennessee to reinstate operations following the "disasters to our arms" there. Georgian troops had been sent to Virginia in July, additional Georgians would be moved to Tennessee also. The Confederate government required a withdrawal from seaboard forces into the interior of South Carolina and Georgia to better secure the breadbasket plantations feeding the armies. In Florida, only the Apalachicola River had to be defended at all costs because Federal gunboats could penetrate so deeply into the Georgia interior.
On Lee's transfer to Richmond, he detailed urgent defense construction, then he called on Lawton's "earnest and close attention" to the Federal's probable approach to the city. "It looks now as if he would take the Savannah River". Guns located in island batteries were to be removed to the mainland in and around Savannah's defensive lines. Obstructions in the river above the city were to be set by hands provided by upriver planters in the event of an envelopment by way of

. "Every effort must be made" to retard or prevent further progress of the enemy directly upriver on the Savannah River approaches. "If he attempts to advance by batteries on the marshes or islands, he must be driven back, if possible." Scouts were ordered out "so as to discover his first lodgment, when they can be broken up." An additional three-gun
battery at MacKay's Point was not intended to stop federal gunboats in force, but with Tattnall's gunboat support, they could prevent Federal batteries from being built on Elba Island to threaten Old Fort Jackson.

Savannah's existing
Fort Jackson, about three miles downriver from the city, was supplemented with two additional batteries. Defenders built fire barges. Lee first placed a battery at Causton's Bluff commanding navigable estuaries leading to the Savannah River behind Fort Pulaski. Then he added another battery situated farther upriver on Elba Island, blocking all river approaches to Savannah. The Union naval commander,

On November 26 Tattnall's flag,
CSS ''"Old" Savannah'', in company with ''Resolute'' and ''Sampson'' sortied out from under Fort Pulaski's guns in a "brave but brief" attack on the Union ships outside the bar, driving them out to sea. Tattnall's squadron withdrew up the Savannah River for refit and two days later, the same three resupplied the fort with six months provisions, despite "the spirited opposition of Federal ships". ''"Old Savannah'' was partially disabled but returned to harbor. ''Sampson'' received considerable damage, returning to patrol the Savannah River only in mid-November the following year.
Siege

Following a reconnaissance of the ground, Gillmore proposed the unconventional plan to reduce Fort Pulaski with mortars and rifled guns. Sherman approved the plan, but not the promise of the rifled guns. His endorsement was qualified, believing gunnery effect would be limited, "to shake the walls in a random manner." But the innovative weaponry in the event made his deployed 10,000-man assault force unnecessary.
Of the two senior military commanders leading up to the engagement, neither Union general, Sherman, nor Confederate general, Lee believed the fort could be captured by bombardment alone.
Approaches
Two sites for Federal batteries were selected upriver from the fort to cut it off from Savannah, just as Lee had anticipated. The first was at Point Venus at the east end of Jones Island along the north bank of the Savannah River North Channel. Tattnall had sunk a schooner to obstruct the northward channel connecting the river to the Union-held Port Royal, and he patrolled the river with Confederate gunboats. The Federals had to clear the obstruction on their most direct supply line first; it required three weeks. A camp and supply depot was established on the next island north, Dawfuskie Island.
Tattnall's gunboats still commanded the lower river around Point Venus. As a part of Lee's active defense, the Confederate's Savannah River Squadron launched continuous patrols. Their naval gunnery required the work along the river by Union besiegers to be done at night. The Federal's guns had to be pulled by hand through swamp over moveable tram sections, the men working in brackish alligator-infested marsh, sinking in over their waist most of the day. The artillery then had to be placed on board-and-bag platforms to avoid their loss by sinking into the morass. The soldiers rested during the day.
[Victor, op. cit. p.106]
By Lee's estimation, the fort could not be reduced by bombardment or direct assault, only by starvation, and would be secure as long as supplies could be built up. The last Confederate supply ship to Fort Pulaski was the small workhorse

''Ida''. On February 13, it was on a routine run to the fort down the North Channel. The new battery of Federal heavy guns on the north bank opened up for the first time. The old side-wheeler ran for Pulaski and the battery got off nine shots before the guns recoiled off their platforms. Union troops went back to work modifying platform construction and resetting the cannon. Two days later ''Ida'' ran up the South Channel under the extinguished lighthouse and returned to Savannah through Tybee Creek.
[Fort Pulaski – National Monument, Historical Handbook, NPS, Op. Cit.]
Once the Union battery at Venus Point was disclosed, Confederate gunboats engaged in gunnery duels, but they were driven off.
Over the next week, the besiegers completely surrounded the Fort. Federals built another battery on the Savannah River across from Venus Point. They threw a

line between Savannah and Cockspur Island. Two infantry companies entrenched nearby to ward off Confederate raiding activity and a gunboat was detailed to patrol the channel and support the infantry. By late February 1862, no supplies or reinforcements could get in; the Confederate garrison could not get out. The last link of communications was a weekly swamp swimming courier.
At the end of February Tattnall laid plans for an amphibious assault on the two advanced batteries at Venus Point and Oakley Island. Lee personally interceded. Preparations at Old Fort Jackson were not completed. Although Tattnall's flagship had been put back into service since the Squadron's January resupply sortie, one of the three gunboats was still seriously disabled. Lee reasoned that if Tattnall's plan failed, the city itself would be open to attack. The three-to-seven exchange had not gone well for the defenders of Savannah. A possible two-to-seven match against ships with superior armament did not promise better. No further consideration was given to relief of the fort; in any case, it had perhaps sixteen weeks of provisions left in store. Meanwhile, Federal emplacements continued to improve on Jones and Bird islands, Venus Point and other points along the river. During the Federal bombardment of Fort Pulaski, April 10–11, "Old ''Savannah''" participated in counter-battery fire with besieging Union guns.

Heavy caliber rifled cannon which the Federals needed to reduce Pulaski had arrived nearby in February, at which time Gillmore decided to locate the batteries at the northwestern tip of Tybee Island nearest the fort.
[NPS battle description, op.cit.] By March, Gillmore was offloading siege materiel onto Tybee Island. Roads had to be laid down, gun emplacements excavated, magazines and bomb-proofs constructed. As the work progressed southwesterly nearing the fort, in the last mile the Union troops came under fire from the fort's gunners. A ranging shot said to be aimed by Colonel Olmstead himself cut a Union soldier in two. The following bombardment from elevated fort guns effected mortar barrages that forced all construction to proceed on Tybee Island by night. Each morning the uncompleted elements of siege construction were camouflaged against the fort's spotters.
To land the cannon onto Tybee Island, artillery pieces were taken off transports, set on rafts at high tide, and pitched into the surf near shore. At low tide, manpower alone would drag the guns up the beach. Two hundred and fifty men were required to move a 13-inch mortar along on a sling cart. Later Union amphibious operations would employ "contraband" (escaped slave) labor for much of this work. Along the two-and-a-half mile front, their engineers had to construct almost a mile of corduroy road made of bundles of brushwood to keep the guns from sinking into the swamp. While offloading proceeded day and night according to the tides, Confederate bombardment from Fort Pulaski gunners required all Federal movement into the island limited to night time. After a month of work, 36 mortars, heavy guns and rifled cannon were in position.
One of the two 13-inch mortars of Battery Halleck at range was given the task of signaling the opening of the bombardment. The battery would proceed by shelling the arches of the north and northeast faces with plunging fire, "exploding after striking, not before".
The four batteries closest to the fort were each given specific firing missions. Battery McClellan at a range of with two 84-pounder and two 64-pounder

Their mission was to fire on the barbette guns until silenced, then switch to percussion shells onto the southeast walls and adjacent embrasure, at a rate of 10–12 rounds an hour to effect wall penetrations for the planned infantry assaults to come later.

The Confederate gunnery was described by the Federal commander as "efficient and accurate firing ... great precision, not only at our batteries, but even at the individual persons passing between them."
As the day wore on, counter-battery fire from Fort Pulaski was gradually silenced as their guns were either dismounted or rendered unserviceable.
Two of the Federal 10-inch columbiads jumped backwards off their carriages. The 13-inch mortars placed less than 10% rounds on target. However, Federal fire proved effective from Parrott and James rifles, and working columbiad guns. There ensued a lull from the fort, but the Confederate gunners re-opened an energetic counter battery duel that required the Parrotts to give up their wall assignment and concentrate on the working Confederate guns until they were re-silenced. By nightfall the wall at the southeast corner had been breached.
Under periodic harassing bombardment throughout the hours of darkness, Olmstead's garrison put several guns back into service.
Overnight, Du Pont's flagship USS ''Wabash'' detached 100 crew to man four of the 30-pounder Parrott rifles. In the morning, with the wind picking up right to left and affecting shell trajectory, the Union artillery resumed the bombardment, concentrating fire to enlarge the opening. The Georgia gunners again found targets, described in dispatches as Rebel "firing ... good all the morning, doing some damage". At the same time, the Parrott rifles and Columbiads opened a great gap in the wall, sending shot across the interior of the fort and against the northwest powder magazine containing twenty tons of powder. Regarding his situation as hopeless, Olmstead surrendered the fort at 2:30 p.m. that day.
Gillmore reported in his after-action assessment of the siege by his artillery, "Good rifled guns, properly served can breach rapidly" at 1600–2000 yards when they are followed by heavy round shot to knock down loosened masonry. The 84-pounder James is unexcelled in breaching, but its grooves must be kept clean. The 13-inch mortars had little effect.

. Damage to the fort was repaired in six weeks, and the Confederates made no attempt to retake it.
The city of Savannah itself remained in Confederate hands until the arrival of William Tecumseh Sherman in December 1864, when he
marched to the sea.
Postwar, it was determined that heavy rifled cannon made masonry fortifications obsolete, revolutionizing
coastal defense as much as the
Battle of the USS Monitor and CAA Virginia had for warships.
The rapid reduction of Fort Pulaski was used to justify stopping work on masonry forts and led to a brief period of new construction of earthwork forts in the 1870s.

, the bombardment was diffuse and scattered, without any real damage to the fort made by the many shots aimed at the fort's flagpole. Admiral Porter adopted Gillmore's gunnery tactics for the second attack, assigning targets until they were destroyed. The January 1865 bombardment dismounted 73 of the fort's 75 guns and mostly shot away the fort's palisade.

CSS ''Georgia'' (1863). Closure of gaps and connections between railways in Savannah, Augusta, and Charleston allowed timely movement of troops and supplies to
besieged Charleston from late 1862 through 1864.
"Lessons learned" by the Confederates were immediately incorporated into the defenses of Charleston, SC. On his release as a prisoner-of-war, Colonel Olmstead was assigned engineer and gunnery duty there. Repeated Union naval and amphibious assaults between 1862 and 1865 failed. Both Union gunboats and ironclads repeatedly suffered substantial damage and loss by Confederate gunnery and mines.
