"I have the honour to bring to your Excellency's notice the following facts:-On Sunday, the 2nd August, very early, the German troops, according to the information which has up to now reached the Grand Ducal Government, penetrated into Luxemburg territory by the bridges of Wasserbillig and Remich, and proceeded particularly towards the south and in the direction of Luxemburg, the capital of the Grand Duchy. A certain number of armoured trains with troops and ammunition have been sent along the railway line from Wasserbillig to Luxemburg, where their arrival is expected. These occurrences constitute acts which are manifestly contrary to the neutrality of the Grand Duchy as guaranteed by the Treaty of London of 1867. The Luxemburg Government have not failed to address an energetic protest against this aggression to the representatives of His Majesty the German Emperor at Luxemburg. An identical protest will be sent by telegraph to the Secretary of State for Foreign Affairs at Berlin."
Telegraph from the Minister of State of Luxemburg to Edward Grey, British Foreign Secretary, August 2, 1914. Britain, France, and Germany were signatories to the 1867 Treaty of London which guaranteed the neutrality of Belgium and Luxemburg. Germany's Schlieffen Plan opened with invasions of the two countries prior to an invasion of France across its northern border.Earlier in the day, the Minister of State had reported to Grey a telegram he had received from Germany's Chancellor, Bethmann Hollweg, assuring the Minister that 'the military measures taken in Luxemburg do not constitute a hostile act against Luxemburg, but are only intended to insure against a possible attack of a French army.'
