After the action of the Coa the enemy quickly possessed themselves of the fortress of Almeida, when there remained nothing between Massena and his kingdom but the simple article of Lord Wellington's army, of which he calculated he would be able to superintend the embarkation within the time requisite for his infantry to march to Lisbon. He therefore put his legions in motion to pay his distinguished adversary that last mark of respect. The Wellingtonians retired slowly before them shewing their teeth as often as favourable opportunities offered, and several bitter bites they gave before they turned at bay--first on the heights of Busaco, and finally and effectually on those of Torres Vedras. The troops of all arms composing the rear guard conducted themselves admirably throughout the whole of that retreat, for although the enemy did not press them so much as they might have done, yet they were at all times in close contact, and many times in actual combat, and it was impossible to say which was the most distinguished--the splendid service of the horse artillery, the dashing conduct of the dragoons, or the unconquerable steadiness and bravery of the infantry. It was a sort of military academy which is not open for instruction every day in the year, nor was it one which every fond mamma would choose to send her darling boy to, calculated although it was to lead to _immortal_ honours. A youngster (if he did not stop a bullet by the way) might commence his studies in such a place with nothing but "the soft down peeping through the white skin," and be entitled to the respect due to a beard or a bald head before he saw the end of it. It is curious to remark how fashions change and how the change affects the valour of the man too. The dragoon since the close of the war has worn all his hair below the head and none on the top it, and how fiercely he fought in defence of his whiskers the other day when some of the regiments were ordered to be shaved, as if the debility of Samson was likely to be the result of the operation. My stars! but I should be glad to know what the old royal _heavies_ or fourteenth and sixteenth _lights_ cared about hairs at the period I speak of, when with their bare faces they went boldly in and bearded muzzles that seemed fenced with furze bushes; and while it was "damned be he who first cries hold--enough!" they did hold enough too, sometimes bringing in every man his bird, mustachoes and all. In those days they seemed to put more faith in their good right hand than in a cart-load of whiskers, for with it and their open English countenances they carved for themselves a name as British dragoons, which they were too proud to barter for any other.
