The energy and zeal of the English commander had been in strange contrast to Napoleon's growing apathy; Wellington had further strengthened his line by two Brunswick regiments and Mercer's battery, and at the last by Adam's brigade with the King's Germans under Dupont. This done, his stand had been superb to the last. Yet he was now at the end of his resources. It was six, and to his repeated messages calling for Blücher's aid there had been no response. Although a portion of Bülow's men had been fighting for more than an hour, yet the Prussian army was not yet fully engaged and he himself, having no reinforcement nor relief, seemed face to face with defeat. Baring had held La Haye Sainte with unsurpassed gallantry; his calls for men had been answered, but his requisitions for ammunition were strangely neglected. Ney, seeing how vain his cavalry charges were, withdrew before the last one took place, arrayed Bachelu's division, collected a number of field-pieces, and fell furiously, with cannonade and bayonet charge, upon the farm-house. His success was complete; the garrison fled, his pursuit was hot, and, leading in person, he broke through the opposing line at its very heart. Had he been supported by a strong reserve, the battle would have been won. Müffling, Wellington's Prussian aide, dashed away to the Prussian lines, and, as he drew near the head of Ziethen's division, shouted: "The battle is lost if the corps do not press on and at once support the English army." Ney's adjutant, demanding infantry to complete the breach he had made, was received by Napoleon with petulance. One brigade from Bülow's corps had attacked at about half-past four; repulsed at first, their onset was growing fiercer, for two other brigades had come in. Soult had opposed Ney's waste of cavalry. But the latter was desperate, and with the other generals was displaying a wilfulness bordering on insubordination. A portion of the guard had just been detached for Lobau's support. To Ney's demand for infantry the Emperor replied: "Where do you expect me to get them from? Am I to make them?" In truth, his mind and energies were now more concerned with Blücher than with Wellington, and he was already fighting the advance of Bülow in his plans. But had the old Bonaparte spirit moved the chieftain to put himself at the head of what remained of the guard infantry, and to make a desperate dash for Ney's support, a temporary advantage would almost certainly have been won; then, with a remnant flushed by victory, he could have turned to Lobau's assistance before the main Prussian army came in. Thus was lost Napoleon's one chance to deal Wellington a decisive blow.
