Grouchy denied having received this order; neither of the officers intrusted with it ever revealed himself; the original of it has never been found; and in subsequent orders issued next day there is no mention of, or reference to, any such message. Either the declaration, twice made at St. Helena, was due to forgetfulness, being an account of intentions not carried out, or else it was put forward to explain the result of the campaign as due to his lieutenant's inefficiency. Grouchy must have had an uneasy conscience, since for thirty years he suppressed the text of the Bertrand order, which was not on the order-book because it had not been dictated to Soult; and when, after falsely claiming for the duration of an entire generation that he had acted under verbal instructions, he did publish it, he gave, at the same time, a mutilated version of his own report from Gembloux, sent on the night of the seventeenth, changing his original language so as to show that he had never looked upon the separation of the allies as his chief task, but that what was uppermost in his mind was an attack on the Prussians. It was two in the morning of the eighteenth when the letter of Grouchy, written about four hours earlier, arrived at Napoleon's headquarters. Both the Emperor and Soult knew by that time that the whole of Bluecher's army was moving to Wavre; yet they did not give this information, nor any minute directions, to the returning messenger. Grouchy, therefore, was left to act on his own discretion, his superior doubtless believing that the inferior would by that time himself be fully informed, and would hasten to throw himself, like an impenetrable wall, between the Prussians and the Anglo-Belgian army. By the defenders of Napoleon Grouchy is severely criticized for not having marched early in the morning of the eighteenth to Moustier, where, if energetic, he could have carried over his army to the left bank of the river by eleven o'clock, thus placing his force within the sphere of Napoleon's operations. Perhaps he would have been able to prevent the union of the opposing armies, or, if not that, to strengthen Napoleon in his struggle. It is proved by Marbot's memoirs that this is what Napoleon expected. On the other hand, excellent critics present other very important considerations: the line to Moustier was over a country so rough and miry that after a torrential rain the artillery would have been seriously delayed, and Prussian scouts might well have brought down a strong Prussian column in time to oppose the crossing there or elsewhere. Grouchy, moreover, could not know that Wellington would offer battle in front of the forest of Soignes--a resolution which, in the opinion of Napoleon and many lesser experts, was a serious blunder. He appears to have been positive that the two armies were aiming to combine for the defense of Brussels; finally, when from Walhain the sound of the firing at
