The "Race to the Sea"

100 years ago today, following the stopping of the German advance into France at the First Battle of the Marne, the German and Anglo-French armies began trying to out-flank each other to the north.

Neither side was able to do it. The digging-in had already begun and within a month, the trench lines would be more-or-less fixed until the German Spring Offensive began in 1918.

The German Spring Offensive had much the same result as the Battle of the Bulge would, 36 years later, and for much the same reason: The German army was unable to logistically sustain the advance.
