The word "Infantry" is said to owe its origin to one of the Spanish Infantas, who, hearing that her father had been defeated by the Moors, raised a body of foot-soldiers, and placing herself at their head, defeated the infidels. In memory of her bravery, foot-soldiers were henceforth styled Infantry. * * * * * The Moors never could obtain a footing north of the Pyrenees; yet, despite the invariable want of success attending their attempts, they made constant incursions into France, besieging towns, burning villages, and ravaging the open country. Amongst other cities besieged by them was Carcassonne, situated on the banks of the river Aude, governed in those days by queen Carcas, famous for her military prowess. When Charlemagne, a few years previously, besieged the city, it was defended so courageously that he permitted the queen to retain the sovereignty. The Saracens, ridiculing the notion of a female warrior, declared that, in place of fighting, she ought to be spinning. This contemptuous speech, spoken immediately under the city walls, was overheard by queen Carcas. Arming herself with a lance, to which, as if it had been a distaff, she attached a quantity of hemp, she set the hemp on fire, and rushed into the midst of the Saracens, who fled, terrified, in all directions. The shield and lance of queen Carcas may yet be seen at Carcassonne. Over the city gate there is an effigy of the royal heroine, with the inscription "Carcas sum." * * * * * While the South of Europe was overrun by the Saracens, England, Ireland, and Scotland were harassed by the terrible Danes, who for several centuries kept these islands in constant terror. The most powerful opponent of the Danes in England was, as everyone knows, King Alfred the Great. During the latter years of his reign, the land was tolerably secure from invasion; but after his death the Vikings and their wild followers came swarming over the country again, burning, plundering, massacring, just as they had done before Alfred drove them away. Elfrida, the eldest daughter of King Alfred, inherited all her father's courage and warlike spirit, and, like him, proved an implacable foe to the Danes. She was married early to Ethelred, Earl of Mercia; and on his death the government of the province devolved upon the widow. And nobly did she fulfil her trust. Mercia was greatly harassed by the Danes--as, indeed, was the entire country in those days. The Welsh joined in alliance with the invaders, and would have marched to their aid but for the promptitude of Elfrida, who entered Wales, 916, at the head of an army, and took Brecknock by storm, capturing therein Queen Anghared and many of her attendants. The "Lady of Mercia" had another motive in this invasion, which rendered Wales tributary to the Saxons; and this motive was the desire to avenge the death of the good Abbot Egbert, whom the Welsh had slain.
