Posted this 90 minute event. Good evening everyone. Can everyone carry while . Good. Im mary mclachlan. Id like to welcome all of you tonight to what promises to be a very stimulating program on the Union General william t sherman. For i begin and i introduce our speaker, id like to remind everyone to check their cell phones and make sure that they are turned off. And also remind everyone that photos are prohibited during Smithsonian Association programs. And lastly, we are delighted to have the cspan History Channel program filming tonight. Jeff shaara will be happy to stay questions at the end of the program. We have mike a mic so cspan can capture your questions. If you will raise your hands we will just wait, if you could, to hold off on asking your questions until you have that microphone in your hand. It is a pleasure to welcome our speaker jeff shaara to the smithsonian. Jeff was last year in 2013 when he presented an Outstanding Program on the battle of vicksburg. Prior to that
