Peace was still possible, however, or so Sir Edward Grey hoped; and, while immediately rejecting, as he was in honour bound to do, Germany's proposal with regard to Belgium, he made the new suggestion of a European Council--a Council to which these problems, even at the eleventh hour, might be submitted to avert disaster. This plan was also destined to be fruitless. On July 31st, Germany sent a note to Russia demanding the instant dispersal of her armies, and requesting a favourable answer by eleven o'clock on Saturday, August 1st; and it was on the same day that Sir Edward Grey asked both Germany and France if they would guarantee the integrity of Belgium, always provided that this was not infringed by any other Power. To this France assented at once, but Germany made no reply. Such was the position on Friday, and, on the Saturday afternoon, August 1st, Germany declared war on Russia, following this up, early on Sunday morning, with the invasion of Luxembourg by part of her advanced armies. This was the day on which the remainder of our naval reservists, including all naval and marine pensioners up to the age of fifty-five, {11} were called to the colours--the plans for their mobilization, reception, and embarkment, in any such event as had now arisen, having been carefully prepared and coördinated with the preliminary steps required of all other Government Departments, and included in the War Book, compiled by the Committee of Imperial Defense, under the presidency of Mr. Asquith, then Prime Minister. Simultaneously, or rather on the previous Saturday afternoon, an order to mobilize had been received at Dartmouth--the Royal Naval College in which, and in the _Britannia_ before it, so many generations of officers had received their first training. Already, on the preceding Tuesday, the cadets had been summoned to the Quarter Deck, as the big recreation hall was called, and told by the Captain that, in the event of war, they would certainly be mobilized--the six "terms" into which the cadets were divided, being ordered to report in three groups at Chatham, Portsmouth, and Devonport, in this order of departure.
