Facts, however, are stronger evidence than words; and this confession on Wellington's part is inconsistent with the circumstance that he had not hurried to retrieve the time he is represented as having owned that Napoleon had gained on him--that he had, on the contrary, allowed his adversary to gain several hours more. Wellington's combination of caution and decision throughout this momentous period is a very interesting study. It was not until 3 P.M. (of the 15th) that there reached him tidings almost simultaneously of firing between the outposts about Thuin and that Ziethen had been attacked before Charleroi, the two places ten miles apart and both occurrences in the early morning. Those affairs might have been casual outpost skirmishes; and the Duke, in anticipation of further information, took no measures for some hours. At length, in default of later tidings he determined on the precautionary step of assembling his divisions at their respective rendezvous points in readiness to march; further specifically directing a concentration of 25,000 men at Nivelles on his then left flank, when it should have been ascertained for certain that the enemy's line of attack was by Charleroi. These orders were sent out early in the evening--"between 5 and 7." Later in the evening came a letter from Blücher announcing the concentration of the Prussian army to occupy the Ligny fighting position, in which disposition Wellington acquiesced; but, still uncertain of Napoleon's true line of attack--his conviction being, as is well known, that Napoleon should have moved on the British right--he would not definitely fix the point of ultimate concentration of his army until he should receive intelligence from Mons. But Blücher's tidings caused him to issue about 10 P.M. a second set of orders, commanding a general movement of the army, not as yet to any specific point of concentration but in prescribed directions towards its left (eastward). At length, when the news came from Mons that he need have no further serious solicitude about his right since the whole French army was advancing by Charleroi, he saw his way clear. Towards midnight, writes Müffling the Prussian Commissioner at his headquarters, Wellington informed him of the tidings from Mons, and added: "The orders for the concentration of my army at Nivelles and Quatre Bras are already despatched. Let us, therefore, go to the ball."
