As two renowned military strategists faced off against each other at the Battle of Gettysburg, they took opposite approaches for rallying their troops, with pivotal consequences for the Civil War.

How do the lessons learned during this historic battle still apply today? Jeff McCausland recounts this story, and other lessons he's learned about leadership during his time in the military, in a new book: Battle Tested! co-authored with Tom Vossler. 

Dr. Jeff McCausland is a retired Colonel from the U.S. Army, former Dean of Academics at the U.S. Army War College, and a National Security Consultant for CBS News - which means he's been a frequent guest with Dave Ross on Seattle's Morning News.
