He soon discovered that she was of heroic mould, however, for though he himself led the storming-parties, she on her side, urging on her men in person, hurled back his every attack. The Lady Agnes was quite fearless, and treated the siege as if it were a pastime to be enjoyed. When the English, with machines made for the purpose, hurled heavy stones against the walls, Black Agnes would call one of her maidens with a napkin to wipe off the dust that they made! The biggest of all the English war-machines was called a sow, and when it was brought to the walls the countess cried out in rough jest that it was surrounded by little pigs. At the same moment a mass of rock, which she had caused to be loosened, was hurled by her men on to the English, crushing their sow and many soldiers with it. At last there seemed a chance for the English. Near midnight a Scot came into their camp, saying that he was ready to betray the castle for a reward. The Earl of Salisbury and some chosen knights rode carefully forward, and found the gate open and the portcullis raised, as the man had promised. But for all that, they doubted if Black Agnes could so far relax her vigilance; wherefore instead of the earl entering first, he sent forward a retainer. His caution was soon justified, for no sooner had this man passed the gate than the portcullis fell. It was a trick to capture the earl, but the Scots were disappointed this time. The gallant English lord was loud in admiration of the brave Scottish lady who was thus defying him. Once when examining the defences with a lieutenant, an arrow struck his companion dead. "The countess’s love-arrows pierce to the heart," said Salisbury, on his return to the camp. Despite the courtly manner in which the well-bred baron referred to the lady, however, he did not relax his efforts to overcome her. Salisbury’s land forces had now surrounded the castle on the land side, while his ships at sea completed the blockade. The garrison was threatened with starvation. Greater and greater became the privations of the heroic defenders. The countess, no less brave than ever, hoped on, though ground for hope grew less and less. She could not bring herself to think of defeat, and her brave, bright face still gave courage and inspiration to all.
