Both U.S. President
Abraham Lincoln and General Ulysses S. Grant had serious reservations about Sherman's plans. Still, Grant trusted Sherman's assessment and on November 2, 1864, he sent Sherman a telegram stating simply, "Go as you propose." The march began on November 15. Sherman recounted in his memoirs the scene when he left at 7 am the following day: Sherman's personal escort on the march was the
1st Alabama Cavalry Regiment, a unit made up entirely of Southerners who
remained loyal to the Union. The two wings of the army attempted to confuse and deceive the enemy about their destinations; the Confederates could not tell from the initial movements whether Sherman would march on
Macon,
Augusta, or
Savannah.
Howard's wing, led by Kilpatrick's cavalry, marched south along the railroad to
Lovejoy's Station, which caused the defenders there to conduct a fighting retreat to Macon. The cavalry captured two Confederate guns at Lovejoy's Station, and then two more and 50 prisoners at
Bear Creek Station. Howard's infantry marched through
Jonesboro to Gordon, southwest of the state capital,
Milledgeville. Slocum's wing, accompanied by Sherman, moved to the east, in the direction of Augusta. They destroyed the bridge across the
Oconee River and then turned south. The first real resistance was felt by Howard's right wing at the
Battle of Griswoldville on November 22. Confederate Maj.
Gen. Wheeler's cavalry attacked Brig. Gen. Kilpatrick's cavalry, killing one, wounding two and capturing 18. The infantry brigade of
Brig. Gen. Charles C. Walcutt arrived to stabilize the defense, and Gen. Wheeler's militia launched several hours of badly coordinated attacks, eventually retreating with about 1,100 casualties (of which about 600 were prisoners), versus the Union's 100. At the same time, Slocum's left wing approached the state capital at
Milledgeville, prompting the hasty departure of
Governor Joseph Brown and the state legislature. On November 23, Slocum's troops captured the city and held a mock legislative session in the capitol building, jokingly voting Georgia back into the Union. Several small actions followed. Wheeler and some infantry struck in a rearguard action at Ball's Ferry on November 24 and November 25. While Howard's wing was delayed near Ball's Bluff, the 1st Alabama Cavalry (a Federal regiment) engaged Confederate pickets. Overnight, Union engineers constructed a bridge away from the bluff across the
Oconee River, and 200 soldiers crossed to
flank the Confederate position. On November 25–26 at
Sandersville, Wheeler struck at Slocum's advance guard. Kilpatrick was ordered to make a feint toward Augusta before destroying the railroad bridge at Brier Creek and moving to liberate the Camp Lawton
prisoner of war camp at
Millen. Kilpatrick slipped by the defensive line that Wheeler had placed near Brier Creek, but on the night of November 26 Wheeler attacked and drove the 8th Indiana and 2nd Kentucky Cavalry away from their camps at Sylvan Grove. Kilpatrick abandoned his plans to destroy the railroad bridge and he also learned that the prisoners had been moved from Camp Lawton, so he rejoined the army at
Louisville. At the
Battle of Buck Head Creek on November 28, Kilpatrick was surprised and nearly captured, but the
5th Ohio Cavalry halted Wheeler's advance, and Wheeler was later stopped decisively by Union barricades at Reynolds's Plantation. On December 4, Kilpatrick's cavalry routed Wheeler's at the
Battle of Waynesboro. More Union troops entered the campaign from an unlikely direction. Maj. Gen.
John G. Foster dispatched 5,500 men and 10 guns under Brig. Gen.
John P. Hatch from
Hilton Head, hoping to assist Sherman's arrival near Savannah by securing the
Charleston and Savannah Railroad. At the
Battle of Honey Hill on November 30, Hatch fought a vigorous battle against G.W. Smith's 1,500 Georgia militiamen, south of Grahamville Station, South Carolina. Smith's militia fought off the Union attacks, and Hatch withdrew after suffering about 650 casualties, versus Smith's 50. Sherman's armies reached the outskirts of Savannah on December 10 but found that Hardee had entrenched 10,000 men in favorable fighting positions, and his soldiers had flooded the surrounding rice fields, leaving only narrow causeways available to approach the city. Sherman was blocked from linking up with the
U.S. Navy as he had planned, so he dispatched cavalry to Fort McAllister, guarding the
Ogeechee River, in hopes of unblocking his route and obtaining supplies awaiting him on the Navy ships. On December 13, William B. Hazen's division of Howard's wing stormed the fort in the
Battle of Fort McAllister and captured it within 15 minutes. Some of the 134 Union casualties were caused by torpedoes, a name for crude
land mines that were used only rarely in the war. Now that Sherman had contact with the Navy fleet under Rear Admiral
John A. Dahlgren, he was able to obtain the supplies and siege artillery he required to
invest Savannah. On December 17, he sent a message to Hardee in the city: Hardee decided not to surrender but to escape. Historian Barrett assesses that Sherman could have stopped Hardee, but failed to because he was hesitant to overcommit his forces. On December 20, Hardee led his men across the
Savannah River on a makeshift pontoon bridge. The next morning,
Richard Dennis Arnold, Savannah's mayor, along with a delegation of aldermen and ladies of the city, rode out (until they were unhorsed by fleeing Confederate cavalrymen) to offer a proposition: The city would surrender and offer no resistance, in exchange for General Geary's promise to protect the city's citizens and their property. Geary telegraphed Sherman, who advised him to accept the offer. Arnold presented him with the key to the city, and Sherman's men, led by Geary's division of the XX Corps, occupied the city the same day. ==Aftermath==
