Battle of Lorraine

The Battle of Lorraine (14 August – 7 September 1914) was a battle on the Western Front during the First World War. The armies of France and Germany had completed their mobilisation, the French with Plan XVII, to conduct an offensive through Lorraine and Alsace into Germany and the Germans with Aufmarsch II West, for an offensive in the north through Luxembourg and Belgium into France, supplemented with attacks in the south to prevent the French from transferring troops to the greater threat in the north.

Background

Belgium

Belgian military planning was based on the assumption that other powers would uphold Belgian neutrality by expelling an invader. The likelihood of a German invasion did not lead the Belgian government to see France and Britain as potential allies nor did it intend to do more than protect its independence. The Anglo-French Entente (1904) had led the Belgians to perceive that the British attitude to Belgium had changed and that they would fight to protect Belgian independence. A General Staff was formed in 1910 but the Chef d'État-Major Général de l'Armée, Lieutenant-Général Harry Jungbluth was retired on 30 June 1912 and not replaced by Lieutenant-General Chevalier de Selliers de Moranville until May 1914.

Moranville began planning for the concentration of the army and met railway officials on 29 July. Belgian troops were to be massed in central Belgium, in front of the National redoubt of Belgium ready to face any border, while the Fortified Position of Liège and Fortified Position of Namur were left to secure the frontiers. On mobilisation, the King became Commander-in-Chief and chose where the army was to concentrate. Amid the disruption of the new rearmament plan, the disorganised and poorly trained Belgian soldiers would benefit from a central position to delay contact with an invader but it would also need fortifications for defence, which were on the frontier.
