from the period October 1942 to May 1943, then to Camp Forrest, Tennessee, between May 1943 to 9 November 1943, and finally Camp Atterbury, Indiana, from 10 November 1943 to 26 January 1944. Overseas: 11 February 1944 Combat chronicle After training in the United States for just over two years, the 30th Infantry Division, under the command of Major General Leland Hobbs, arrived in England, 22 February 1944, and trained for the Allied invasion of Normandy until June. It landed at Omaha Beach, Normandy, on 11 June 1944, five days after the initial D-Day landings of 6 June 1944, secured the Vire-et-Taute Canal, crossed the Vire River on 7 July. Beginning on 25 July, the 30th Division spearheaded the Saint-Lô break-through of Operation Cobra, which was intended to break out of the Normandy beachhead, thus ending the stalemate that had occurred. During the operation, on both 24 and 25 July, the 30th Division encountered a devastating friendly fire incident. As part of the effort to break out of the Normandy hedgerows, US Army Air Forces (USAAF) bombers from England were sent to carpet bomb a one-by-three-mile corridor of the German defenses opposite the American line. However, USAAF planners, in complete disregard or lack of understanding of their role in supporting the ground attack, loaded the heavy B-24 Liberator and B-17 Flying Fortress bombers with 500-pound bombs, destroying roads and bridges and complicating movement through the corridor, instead of lighter 100-pound bombs intended as antipersonnel devices against German defenders. Air planners switched the approach of attack by 90 degrees without informing ground commanders, thus a landmark road to guide the bombers to the bombing zone was miscommunicated as the point to begin the bombing run. Start point confusion was further compounded by red smoke signals that suddenly blew in the wrong direction, and bombs began falling on the heads of the American soldiers. There were over 100 friendly fire casualties over the two days, including Lieutenant General Lesley J. McNair, commander of Army Ground Forces under Malisau. The division relieved the veteran 1st Infantry Division near Mortain on 6 August. The German drive to Avranches began shortly after. The 30th Division clashed with the elite 1st SS Panzer Division, and fierce fighting in place with all available personnel broke out. The division frustrated enemy plans and broke the spearhead of the enemy assault in a violent struggle from 7–12 August. After
