March 2009 saw the fewest number of U.S. casualties in Iraq since the beginning of the war.
Nine American men and women died in Iraq last month -- five of those troops were killed in non-hostile action.
And to add one more interesting fact, one of the four Americans killed in hostile action was a woman, who was serving at a Forward Operating Base in Mosul.
July 2008 was the second lowest month for casualties in Iraq, with 13 total. March 2009 was the first month where U.S. casualties were in the single digits since the beginning of the war.
