The Battle of Samawah took place during the 2003 invasion of Iraq as American troops fought to clear the city of Iraqi forces. The city had been bypassed during the advance on Baghdad, leaving the task of clearing it to American paratroopers of the 82nd Airborne Division with mechanized infantry and armor provided by units of the 1st Battalion, 41st Infantry Regiment, and 2-70th Armor Battalions, along with 3rd platoon 59th Chemical Company tasked with finding and removing any potential chemical or biological weapons. The battle was the largest sustained urban combat that paratroopers of the 82nd Airborne had been involved in since World War II.
