Why Was There A Valley Campaign?

Wherein we examine failures of intelligence

.............................................................................................................................................

The first of two posts on mistakes by the North the first week of May 1862.

May 8, 1862, was the date of the Battle of McDowell, the beginning of Stonewall Jackson's legendary Valley Campaign. Much has justly been written about Jackson's operational-level brilliance and an equal amount has unjustly been written about his rather mundane tactics. Only in recent years, have reevaluations of the campaign been conducted, most notably in Peter Cozzens fantastic Shenandoah 1862 which acknowledges the immense personal cost to the soldiers of Jackson's army and, in the words of the friend who gifted the book to me, "bothers to examine the Yankee sources."

The Valley, though technically in the Potomac watershed, has simply been beyond the capacity of your blogger to post on, which means the area that drains directly into the Shenandoah has usually been beyond the scope of this blog. But Jackson's campaign deeply threatened the area we usually cover, and ended up being the strategic center of gravity for the entire Virginia theater. Without Jackson's operation, Joe Johnston, hundreds of miles away on the Virginia Peninsula, would have been unable to fend of McClellan's army, and Richmond would have been scrambling to find defenders in fall 1862 instead of Washington.

Edwin Stanton

It was largely planning mistakes made in Washington at the strategic level from May 8 to May 17 that allowed Jackson to conduct his famous campaign. This post focuses on the first part of those mistakes, the failure in intelligence collection and analysis.

With the demotion of McClellan in March, Secretary of War Edwin Stanton became the Administration's principle war planner. Unlike his predecessor, Simon Cameron, Stanton believed the Secretary should be active in decisions about the prosecution of the war, rather than only concerned with supplying and administering the armies. Stanton signaled this when he added Peter H. Watson as a second Assistant Secretary of War as a condition of joining the Administration himself. Watson was appointed to straighten out and manage the contracts the Department made to supply the army, which was usually a tightly held responsibility of the Secretary in order to bestow political favors.
