The authors were able to access and examine relevant documents, interview numerous participants, and visit U.S. and NATO forces in Bosnia in order to provide readers with an analytical narrative that covers the background to the crisis in Bosnia, the largely ineffectual efforts of the United Nations Protection Force (UNPROFOR) to stop the civil war there between 1992 and 1995, the Dayton Peace Accords of 1995 that produced a framework for ending the civil war and consolidating the peace, the frenetic planning that led to the deployment of U.S. forces as part of the NATO-led multinational force (Operation Joint Endeavor), and the transition of that Implementation Force (IFOR) to the Stabilization Force (SFOR) a year later. The authors shed light on several of the critical military lessons that have emerged from the U.S. experience in Bosnia.
