During his 2009-2010 combat tour in Afghanistan, battalion commander Lt. Col. Michael J. Forsyth kept a daily journal. In it he candidly writes about his daily interactions with the Afghan government, citizens, security forces, and his intermittent conflict with the enemy. As the deployment progresses, the journal reveals that his initial expectations for peace in Afghanistan were tempered by his experiences and encounters. In the process, Col. Forsyth learned critical lessons in leadership and changed his thinking about realistic goals that can be accomplished in Afghanistan. The journal, and its subsequent annotations, also provides a glimpse into how the U.S. Army functions at the unit level and what America’s Soldiers do on a daily basis to prepare for and engage in combat.
