NOTIFICATIONS OF A STATE OF WAR
His Majesty’s Government informed the German Government on August 4th, 1914, that, unless a satisfactory reply to the request of His Majesty’s Government for an assurance that Germany would respect the neutrality of Belgium was received by midnight of that day, His Majesty’s Government would feel bound to take all steps in their power to uphold that neutrality and the observance of a treaty to which Germany was as much a party as Great Britain.
The result of this communication having been that His Majesty’s Ambassador at Berlin had to ask for his passports, His Majesty’s Government have accordingly formally notified the German Government that a state of war exists between the two countries as from 11 p.m. to-day.
