NAPOLEON FRANCIS CHARLES JOSEPH, DUKE OF REICHSTADT, ETC., ETC., SON OF NAPOLEON BONAPARTE.] The second division of the battle was the main attack on Wellington's left by d'Erlon's corps. Between twelve and one a Prussian hussar was captured with a message from Bluecher to Wellington announcing the Prussian advance. At once the postscript was added to the second despatch to Grouchy, already mentioned, and Napoleon made ready for his great effort. Unable to sit his horse, he had dismounted, and, seated at the table on which his map was spread, had been frequently seen to nod and doze. Ney and d'Erlon, left to their own judgment, had evolved a scheme of formation so complex that when tried, as it now was, it proved unworkable. The confusion was veiled by a terrific, continuous, and destructive artillery fire. After some delay, and a readjustment involving preparations against the possible flank attack of the Prussians, d'Erlon's corps advanced in four columns, under Donzelot, Allix, Marcognet, and Durutte respectively. Opposed was Picton's decimated corps, with Bylandt's Dutch-Belgian brigade, which had been all along a target for the strongest French battery, one of seventy-eight guns,[25] and was now to bear the first onset of the French troops. Bylandt's men had stood firm under the awful artillery fire, but their uniforms were like those of the French, and in a melee this fact might draw upon them the fire of their own associates, as later in the day at Hougomont it actually did, and they grew very uneasy. Durutte, on the extreme right, seized Papelotte, but lost it almost immediately. The conflict then focused about La Haye Sainte, where the garden and orchard were seized by an overwhelming force. The buildings had been inadequately fortified, but Major Baring, with his garrison, displayed prodigies of valor, and held them. [Footnote 25: Houssaye says eighty (1815, p. 338).
