attacked a German regimental-sized unit near Carisey, protecting the southern flank of the 4th Armored Division as it drove on Troyes. On 30 August, the Dragoons led the XII Corps assault across the Marne River, with the 2nd Squadron in front of the 80th Infantry Division and the 42nd Squadron in front of the 4th Armored Division. By 2 September, the drive reached the Moselle River near Toul and the 2nd Squadron began scouting for possible crossing points. Despite a failed crossing attempt by 80th Division troops against stiff resistance, the 2nd MCG was active in scouting and screening during this period. On 4 September, B and F Troops of the 42nd Squadron defeated a column of 1,000 German soldiers attempting to attack the XII Corps flank by massing direct fire from their light tanks, and indirect fire from artillery units. On 7 September, the 602nd Tank Destroyer Battalion, equipped with M18 Hellcats, was attached to the 2nd MCG. This allowed the 42nd Squadron to assault and capture Fort de Pont-Saint-Vincent and defeat an enemy counterattack. The 2nd MCG then began to protect the southern flank of the 4th Armored Division as it fought to envelop Nancy on 11 September 1944. They were often engaged in heavy contact against German units while protecting the flanks of the 4th Armored Division's assault. On 16 September, the Dragoons launched a squadron-sized attack on Lunéville. The Germans put up a vigorous defense but could not hold against the 2nd MCG, and retreated. However, on 18 September, elements of the 111th Panzer Brigade counterattacked with "six Panther tanks and two companies of infantry." The Panzers' armor was too thick and the cavalrymen were forced to retreat. This was the beginning of the Battle of Arracourt. Conducting a delaying action, the two squadrons worked in tandem and managed to keep the enemy at bay until 1100, when reinforcements of the 4th Armored Division arrived and beat back the Germans. This battle provides a perfect example of how Mechanized Cavalry Groups were designed to function in World War II. Had it not been for the screening and delaying efforts of the 2nd MCG, the main effort of the Wehrmacht attack would have fallen on the flank of the 4th Armored Division. In late October, the 2nd MCG was assigned to protect the flanks of the 26th Infantry Division by seizing Moncourt Ridge. Despite fierce German resistance,
