There are three definite evidences that before midnight of the 15th Wellington had resolved to concentrate about Quatre Bras, and had issued final orders accordingly--his statement to the Duke of Richmond, his statement to Müffling, and his statement in his official report to Lord Bathurst. Yet Mr. Ropes believes that his decision to that effect "could not have been arrived at very long before he left Brussels" on the morning of the 16th, which he did "probably about half-past seven." He founds this belief on two orders dated "16th June" sent to Lord Hill in the early morning of that day, in which there is no allusion to a concentration at Quatre Bras. But those were merely supplementary instructions as to points of detail; for example, one of them enjoined that a division ordered earlier to Enghien should move instead by way of Braine le Comte, that being a nearer route toward the final general destination of Quatre Bras specified in the earlier (the "towards midnight") orders. The latter orders are not extant, having been lost according to Gurwood, with De Lancey's papers when he fell at Waterloo; but that they must have been issued is proved by the fact that they were acted upon by the troops; and that they were issued before midnight of the 15th is made clear by Wellington's three specific statements to that effect. When the Duke left Brussels for the front on the morning of the 16th he took with him a singularly optimistic paper styled "Disposition of the British Army at 7 A.M., 16th June," which was "written out for the information of the Commander of the Forces by Colonel Sir W. de Lancey," his Quartermaster-General. In the nature of things for the most part guess-work, the wish as regarded almost every particular set out in this document was father to the thought. Wellington was no doubt reasonably justified in accepting and relying on this flattering "Disposition;" but its terms, as Mr. Ropes conclusively shows, simply misled him and caused him also unconsciously to mislead Blücher, both by the expressions of the letter written by him to that chief on his arrival at Quatre Bras and later when he met the Prussian commander at the mill of Brye. Wellington was indeed trebly fortunate in finding the Quatre Bras position still available to him--fortunate that Ney on the previous evening had defaulted from his orders in refraining from occupying it; fortunate that Ney still on this morning was remaining passive; and more fortunate still that it had been occupied, defended, and reinforced by Dutch-Belgian troops not only without orders from him but in bold and happy violation of his orders. Perponcher's division was scarcely a potent representative of the Anglo-Dutch army, but there was nothing more at hand; and pending the coming up of reinforcements Wellington, with rather a sanguine reliance on Ney's maintenance of inactivity, rode over to Brye and had a conversation with Blücher.
