besiegers. Federal preparations required four months. In those four months, Lee developed a defense in depth. Behind Fort Pulaski on the Savannah River, Fort Jackson was improved, and two additional batteries covered river approaches. In the face of the Union superiority in naval, artillery and infantry deployment, Lee was able to block any Federal advance on Savannah, and at the same time, well-trained Georgia troops were released in time to meet McClellan's Peninsula Campaign. The city of Savannah would not fall until Sherman's approach from the interior at the end of 1864. At first, the press spoke to the disappointment of losing Fort Pulaski. Surprised by the effectiveness of large caliber Parrott Rifles in their first deployment, it was widely speculated that only betrayal could have brought overnight surrender to a Third System Fort. Lee was said to have failed to get effective support in the Savannah River from the three sidewheeler gunboats of the Georgia Navy.

Confederate newspaper editorials objected to him replacing Johnston, opining that Lee would be passive, waiting for Union attack. This seemed true, initially; for the first three weeks of June, Lee did not show aggression, instead strengthening Richmond's defenses. However, on June 25, he surprised the Army of the Potomac and launched a rapid series
