The
Gauls worshipped a goddess known as
Dea Matrona ("divine mother goddess") who was associated with the Marne. The Marne was navigable as a free-flowing river until the 19th century. It had one gated 500 m shortcut, the Canal de Cornillon in Meaux, which was built in 1235, the oldest canal in France. Canalisation was started in 1837 and completed to Épernay in 1867. It included a number of canals to bypass the most extravagant meanders. In
World War I, the Marne was the scene of two notable battles. In the
First Battle of the Marne (September 1914), the military governor of Paris, General
Joseph Gallieni, took the initiative in driving the Germans back from the capital, rendering their
war-plan inoperative. In the
Second Battle of the Marne (July-August 1918), the last major German offensive on the Western Front was defeated by an Allied counter-attack, leading eventually to the
Armistice. == Navigation ==
