Colonel Basil Jackson has the following recollections of his experiences on the evening of the 15th June: "I was sauntering about the park towards seven o'clock on the evening of the 15th June, when a soldier of the Guards, attached to the Quartermaster-General's office, summoned me to attend Sir William De Lancey. He had received orders to concentrate the army towards the frontier, which until then had remained quiet in cantonments. I was employed, along with others, for about two hours in writing out 'routes' for the several divisions, foreign as well as British, which were despatched by orderly Hussars of the 3rd Regiment of the German Legion, steady fellows, who could be depended on for so important a service. To each was explained the rate at which he was to proceed, and the time when he was to arrive at his destination; he was directed also to bring back the cover of the letter which he carried, having the time of its arrival noted upon it by the officer to whom it was addressed. "This business over, which occupied us till after nine, De Lancey put a packet into my hand directed to Colonel Cathcart--the present Earl--a thorough soldier, and highly esteemed by the Duke, who then filled, as he had previously done in Spain, the arduous post of Assistant Quartermaster-General to the whole of the cavalry. "'I believe you can find your way in the dark by the cross roads to Ninove,' said Sir William, 'let this be delivered as soon as possible.' "Proud of my commission, I was speedily in the saddle and threading my way, which I did without difficulty. My good nag rapidly cleared the fifteen miles, but ere reaching the above place, then the headquarters of the cavalry, I fell in with one or two orderly Dragoons speeding to out-quarters. I could also perceive lights flickering about in the villages adjacent to my route: indications which satisfied me that the German Hussar previously despatched from Brussels had accomplished his mission. "Here let me stop for a moment to commend the practice in our service of having plenty of well-mounted staff officers ready to convey orders of moment at the utmost speed. On the portentous night in question, several, chiefly belonging to the Royal Staff Corps, a body attached to the Quartermaster-General's department, were employed in conveying duplicates of the instructions previously forwarded by Hussars, in order to guard against the possibility of mistake. The omission of such a precautionary measure at the Prussian headquarters, on the same evening, was attended with disastrous consequences, for Bluecher's order for Bulow's corps to unite with the rest of his army, being entrusted to a corporal, probably wanting in intelligence, he did not deliver it in time, whereby that corps, 30,000 strong, failed to reach Ligny and share in the battle."[33] [Footnote 33: "Recollections of Waterloo," by a Staff Officer, in _United Service Journal_ for 1847, Part III., p. 3.]
