France and England plan for mobilization against Germany

 July 20, 1911: On this date, Sir Henry Wilson, Director of Military Operations on the British General Staff, met in secret with General Auguste Dubail, French Army Chief of Staff, to formulate an  agreement for a joint plan to mobilize 150,000 men in the event that Germany declared war on either nation. Though the Dubail-Wilson plan did not become necessary in 1911, it would be used three years later when World War I broke out.

Per the Dubail-Wilson agreement, the British were to mobilize following intervention, specifying 150,000 men and 67,000 horses to be landed at Havre, Boulogne and Rouen between 4th-12th day of mobilization and be sent to Mauberge region and ready for action on 13th day.

Although it may appear that the agreement had been a result of Germany's actions in the Agadir crisis, it may also had been a result of war games,which indicated that Germany would have moved easily through Belgium and France unless there was early commitment of the British Expeditionary Force ^[1] .
