4. Normandy, France, June – July 1944

The Battle for Normandy which began on June 6 1944 is generally agreed to have lasted until the third week of July. Allied troops fought their way ashore on the Normandy beaches and began moving inland almost immediately, where they encountered something the planners had not adequately taken into account – the hedgerows of the bocage country. While the British concentrated on taking the French town of Caen, which delayed the advance into France for several weeks, the Americans turned toward the capture of the port of Cherbourg. The foothold of the beachhead was expanded rapidly and troops and supplies continued to pour ashore, using the beaches themselves and two artificial harbors, called “mulberries”. But the advancing troops met heavy German resistance at all points, and poor weather often grounded their air support.

Winston Churchill had predicted that the combined casualties of the Allied troops, which included French commandos, and troops from other allied nations, would be about 20,000. The casualties for the first day were heavy, particularly at the American sector of Omaha Beach, and the fighting on French soil, particularly in the bocage – which were ideal for defensive fighting – continued to be high throughout the end of the battle for Normandy. When the operation ended in July, to be soon replaced by the battle across France, 16,293 Americans had been killed in the battle, ranking as the highest of the war to that date, higher than any of the battles of the Pacific War. The fighting continued in the battle of France, which yielded yet higher casualties among the Americans before the end of the year.

3. The Battle for France, 1944

By July 25, 1944, more than 1.5 million troops had landed in France. By the end of the following month their number exceeded 2 million. Additionally thousands of pieces of equipment, tanks and guns, motorized vehicles, and all the accouterments of a mechanized army were on the French coast. By August 1, the American Third Army under George Patton was moving to take Brittany and territory southward towards the Loire Valley. On the fifteenth of August the invasion of southern France was launched, and German troops which had occupied territories in the south of France since the invasion of North Africa began withdrawing eastward. The Americans pushed forward, encountering steady resistance from the Germans as they moved eastward, occasionally launching strong counterattacks as they withdrew.

On September first Eisenhower took direct command of all ground forces in Europe and directed a slowdown of the Allied advance. He continued the strategy of advancing on a broad front, rather than adopting single direct thrusts, as a means of containing German counterattacks and to conserve supplies. The battle across France had freed most of the country from German control by early September, at a heavy cost of life, including for the Americans. From July 25 through September 14, 1944, 17,844 Americans had lost their lives, a number which does not include the casualties from the invasion of Southern France in the Mediterranean. The liberation of most of France had taken just over six weeks of almost constant fighting with a determined enemy who as yet showed no inclination to give up the fight.

2. The Battle of the Bulge, Northern Europe, December 1944 – January 1945

In the morning of December 16, 1944, German columns struck American forces in the Ardennes, in a massive and determined assault which was intended to split the allied forces into four groups and capture the port of Antwerp. The attack was launched in heavy wintry weather, using forces which the allies were unaware that the Germans had gathered on the western front. The weather prevented the allies from resorting to their air superiority to contain the attack. The Americans resisted the attack, at first piecemeal, and then growing more organized, particularly at the northern elbow of the salient the Germans created and at Bastogne, which contained important crossroads. The resistance threw the Germans off schedule, denied the use of some roads which prevented columns from advancing parallel to each other, and gave the Americans time to rush other units to the battlefield.

The German assault included fourteen hundred tanks and over 400,000 troops. Eventually the United States committed over 600,000 men to first stopping the German advance and then reducing the salient – the famous Bulge – which had been created in the Allied lines. By the end of December the Germans were reinforced but by that time the assault was already doomed to failure, following the arrival of reinforcements by the Americans under Patton from the south and clearing weather in January which allowed the Americans to use their P-47s to attack German tanks from the air. The fighting remained fierce as the Germans were pushed back, finally retreating to the defenses of the Westwall, known to Americans as the Siegfried Line. Over 19,200 Americans were killed in the fighting before the battle ended in January, 1945. They included Americans who had surrendered as prisoners of war before being shot by Waffen SS troops in the Malmedy massacre, where at least 84 Americans were murdered.

1. Meuse-Argonne Offensive, France, September – November 1918

While Americans were singing Over There at home in 1918, the American troops which had been sent over there were involved in the deadliest battle of American history. The offensive launched by the American Expeditionary Forces in France involved 1.2 million men, the largest offensive in American military history, one of the Allied attacks known as the Hundred Days Offensive, a series of coordinated attacks designed to end the war to end all wars. The battle was fought in three phases, with the American troops gaining valuable experience and growing confidence in their abilities as it went on. It began with an assault by the Americans towards Sedan, followed by British attacks in Belgium the following day, and French assaults on German positions across northern France. The morale of the Allies was strengthened by the advance of the Americans, who were eager for battle, though inexperienced.

That inexperience showed in the casualties absorbed by the Americans, which were heavy. American forces fought with French tanks, and were supported by the forces of Great Britain and Australia, achieving their goals in splitting the Hindenburg Line, the main German defense perimeter, and driving the Germans backwards. The largest American assaults were in the sector around Verdun, though American units took part in actions to the north as well. During the second phase of the battle the famous Lost Battalion event occurred. By the beginning of November the Americans broke the Hindenburg Line as well as cleared the Argonne Forest, throwing the German defenses in disarray. French forces captured Sedan on November 6. The offensive ended with the ceasefire of November 11, 1918. By that time, in an offensive which lasted less than two months, 26,277 Americans had lost their lives.
