The Battle of Gettysburg and Meuse-Argonne Offensive are both battles fought during what?
Meuse-Argonne Offensive The Meuse-Argonne Offensive, also known as the Maas-Argonne Offensive and the Battle of the Argonne Forest, was a major part of the final Allied offensive of World War I that stretched along the entire Western Front. It was fought from 26 September 1918 until the Armistice of 11 November 1918, a total of 47 days. The Meuse-Argonne Offensive was the largest in United States military history, involving 1.2 million American soldiers. It was one of a series of Allied attacks known as the Hundred Days Offensive, which brought the war to an end. The battle cost 28,000 German lives and 26,277 American lives. It was the largest and bloodiest operation of World War I for the American Expeditionary Force (AEF), which was commanded by General John J. Pershing, and one of the deadliest battles in American history. American losses were exacerbated by the inexperience of many of the troops, and tactics used during the early phases of the operation.
Operation Atlantic Operation Atlantic (18–21 July 1944) was a Canadian offensive during the Battle of Normandy in the Second World War. The offensive, launched in conjunction with Operation Goodwood by the Second Army, was part of operations to seize the French city of Caen and vicinity from German forces. It was initially successful, with gains made on the flanks of the Orne River near Saint-André-sur-Orne but an attack by the 4th and 6th Canadian Infantry Brigades of the 2nd Canadian Infantry Division, against strongly defended German positions on Verrières Ridge to the south was a costly failure.
