The Battle of the Marne by G.H. Perris — Read

Instead of an initial defensive over most of the front, with or without some carefully chosen and strongly provided manœuvre of offence -- as the major conditions of the problem would seem to suggest -- the French campaign opened with a general offensive, which for convenience we must divide into three parts, three adventures, all abortive, into Southern Alsace, German Lorraine, and the Belgian Ardennes. The first two of these were predetermined, even before General Joffre was designed for the chief command; the second and third were deliberately launched after the invasion of Belgium was, or should have been, understood. A fourth attack, across the Sambre, was designed, but could not be attempted.

The first movement into Alsace was hardly more than a raid, politically inspired, and its success might have excited suspicions. Advancing from Belfort, the 1st Army under Dubail took Altkirch on August 7, and Mulhouse the following day. Paris rejoiced; General Joffre hailed Dubail's men as "first labourers in the great work of _la revanche_. " It was the last flicker of the old Gallic cocksureness. On August 9, the Germans recovered Mulhouse. Next day, an Army of Alsace, consisting of the 7th Corps, the 44th Division, four reserve divisions, five Alpine battalions, and a cavalry division, was organised under General Pau. It gained most of the Vosges passes and the northern buttress of the range, the Donon (August 14). On the 19th, the enemy was defeated at Dornach, losing 3000 prisoners and 24 cannon; and on the following morning Mulhouse was retaken -- only to be abandoned a second time on the 25th, with all but the southern passes.
