U.S. Grant saved George Pickett's neck

[LincolnMan]

I found this from the January 1964 Civil War Times magazine about General Pickett:

Pickett's Greatest Triumph

"It is an ironic twist of history that Gen. George E. Pickett is best remembered for his gallant charge at Gettysburg- a military failure- while his most conspicuous success is practically unknown. While Grant and Lee were slugging it out in the Wilderness, Chancellorsville, and Cold Harbor, Pickett was in command of the Department of North Carolina, with headquarters at Petersburg. When Gen. ben Butler, acting under orders from Grant, moved up from Fortress Monroe and disembarked at Bermuda Hundred, Pickett was the only one who realized the danger. While his urgent appeals for help were being disregarded in Richmond, Pickett gathered what troops he could, and went out to meet Butler. Pickett's prompt action saved Petersburg, postponing the final surrender nearly a year."

I don't see in the issue who the author of the quote is. It is included as a side-bar at the end of an article.
