(1.) If we are correct in the view taken above, namely, that Napoleon did not intend to seize Sombreffe on the 15th, because he feared that if Blücher found his line of communications with Wellington occupied in force at Sombreffe, he would retire to the northward, and there form a junction with the Anglo-Dutch army, it would seem at first blush as if Blücher might be expected to take the same course if he found the turnpike to Nivelles occupied in force by the enemy at Quatre Bras. But this seems to be pushing the argument too far. Blücher could hardly be expected to be affected by the report of the occupation of Quatre Bras so much as by the expulsion of Zieten’s Corps from Sombreffe, and by the occupation of that place by the main French army. Theoretically, so to speak, the seizure of any one point on the Namur-Nivelles turnpike ought to produce the same effect on Marshal Blücher’s mind, and, therefore, on his subsequent movements, as the seizure of any other. Yet one can easily see that, practically, this might not be so. On the other hand, there was certainly the risk that Blücher would not fight at or near Sombreffe unless he thought he could count on receiving aid from Wellington, and this expectation could hardly be entertained, if he knew that the French were in possession of Quatre Bras. Still, the importance of preventing Wellington, by an early occupation of Quatre Bras, from assisting the Prussians in their resistance to the attack which he hoped to make upon them the next day, may well have induced Napoleon to give on the 15th to Marshal Ney orders to occupy Quatre Bras at once, and to take the chance of the result of this step being the withdrawal of the Prussian army to Wavre or Brussels.
