The battle once begun, its very various changes,--the resistance of Hougomont; the tenacity of La Haie-Sainte; the killing of Bauduin; the disabling of Foy; the unexpected wall against which Soye's brigade was shattered; Guilleminot's fatal heedlessness when he had neither petard nor powder sacks; the miring of the batteries; the fifteen unescorted pieces overwhelmed in a hollow way by Uxbridge; the small effect of the bombs falling in the English lines, and there embedding themselves in the rain-soaked soil, and only succeeding in producing volcanoes of mud, so that the canister was turned into a splash; the uselessness of Pire's demonstration on Braine-l'Alleud; all that cavalry, fifteen squadrons, almost exterminated; the right wing of the English badly alarmed, the left wing badly cut into; Ney's strange mistake in massing, instead of echelonning the four divisions of the first corps; men delivered over to grape-shot, arranged in ranks twenty-seven deep and with a frontage of two hundred; the frightful holes made in these masses by the cannon-balls; attacking columns disorganized; the side-battery suddenly unmasked on their flank; Bourgeois, Donzelot, and Durutte compromised; Quiot repulsed; Lieutenant Vieux, that Hercules graduated at the Polytechnic School, wounded at the moment when he was beating in with an axe the door of La Haie-Sainte under the downright fire of the English barricade which barred the angle of the road from Genappe to Brussels; Marcognet's division caught between the infantry and the cavalry, shot down at the very muzzle of the guns amid the grain by Best and Pack, put to the sword by Ponsonby; his battery of seven pieces spiked; the Prince of Saxe-Weimar holding and guarding, in spite of the Comte d'Erlon, both Frischemont and Smohain; the flag of the 105th taken, the flag of the 45th captured; that black Prussian hussar stopped by runners of the flying column of three hundred light cavalry on the scout between Wavre and Plancenoit; the alarming things that had been said by prisoners; Grouchy's delay; fifteen hundred men killed in the orchard of Hougomont in less than an hour; eighteen hundred men overthrown in a still shorter time about La Haie-Sainte,--all these stormy incidents passing like the clouds of battle before Napoleon, had hardly troubled his gaze and had not overshadowed that face of imperial certainty.

To increase the security of the watermark, a new binary image encryption algorithm based on TD-ERCS map is presented. The watermark is encrypted by a chaos sequence generated by TD-ERCS map; A novel color image watermarking algorithm is proposed based on discrete chaotic map and 2-dimensions discrete wavelet transform. The watermark is encrypted by the new binary image encryption algorithm, and the encrypted watermark is embed into four sub-bands of the most deep level of blue branch of host image by three-level wavelet transform, and the embedded positions are determined by general cat cha otic map; A novel color-image blind detection watermarking algorithm is proposed based on integer wavelet transform and subsampling. The scrambled watermark is encrypted and embed into the low sub-bands after four sub-images of the Y branch of host image is transformed by two-level wavelet transform, and the embedded positions are determined by Logistic chaotic map, this watermarking scheme can realize blind extraction.
