From the Combat Studies Institute web site:

On Point II is the US Army's first historical study of its campaign in Iraq in the decisive eighteen months following the overthrow of the Baathist regime in April 2003. The book examines both the high-level decisions that shaped military operations after May 2003 as well as the effects of those decisions on units and Soldiers who became responsible for conducting those operations.

The authors, historians at the US Army's Combat Studies Institute at Fort Leavenworth, Kansas, based this account on hundreds of interviews with key participants and thousands of primary documents. Critical chapters in this book address the decision to disband the Iraqi Army, detainee operations (including the incidents at the Abu Ghraib prison), reconstruction efforts, and the Army's response to the growing insurgency.

At the core of On Point II is the dramatic story of how after May 2003, the US Army reinvented itself by transforming into an organization capable of conducting a broad array of diverse and complex "Full Spectrum" operations. This was the new campaign that confronted American Soldiers beginning in May 2003 as they strived to create stability in Iraq.
