He didn't strictly capture any states.
After his occupation of Atlanta, there were still plenty of Confederates in Georgia and Tennessee, but Sherman decided to ignore them and carry out punitive raids on civilians. This had the same effect as capturing the territory.
In December 1864, the Confederate army in Tennessee was routed at Nashville, just as Sherman reached the coast at Savannah (and able to signal to Grant and Lincoln for the first time in six weeks).
Early in 1865, he crossed into the Carolinas, and this brought the war visibly to a close, much more than Grant's terrible, endless Siege of Petersburg.
General Sherman's march was directed toward the coastal port city of Savannah, Georgia, in November-December of 1864. Sherman called the capture of the port a "Christmas gift" for President Abraham Lincoln.

For the 1864 Union campaign, only General Sherman's army was given the explicit goal of cutting Southern rail links. He was to wage a conventional march on Atlanta, and from there cut as many Rebel railway links as possible. Later in 1864, Sherman's plans would be altered.
