The officers, startled by this confident assertion, continued their questions; but now, from a distance, the clang of a bell was heard. The Lexington men cried out at this,-- "The bells are ringing! The towns are alarmed! You are all dead men!" This assertion, which the sound of the bells appeared to confirm, alarmed the officers. If the people should rise, their position would be a dangerous one. They must make their way back. But, as a measure of precaution, they took Revere's horse and cut the girths and bridles of the others. This done, they rode away at full speed, leaving their late captives on foot in the road. But this the two messengers little heeded, as they knew that their tidings had gone on in safe hands. While all this was taking place, indeed, Prescott had regained the road, and was pressing onward at speed. He reached Concord about two o'clock in the morning, and immediately gave the alarm. As quickly as possible the bells were set ringing, and from all sides people, roused by the midnight alarum, thronged towards the centre square. As soon as the startling news was heard active measures were taken to remove the stores. All the men, and a fair share of the women, gave their aid, carrying ammunition, muskets, cartridges, and other munitions hastily to the nearest woods. Some of the cannon were buried in trenches, over which a farmer rapidly ran his plough, to give it the aspect of a newly-ploughed field. The militia gathered in all haste from neighboring villages, and at early day a large body of them were assembled, while the bulk of the precious stores had vanished. [Illustration: THE SPIRIT OF '76.] Meanwhile, momentous events were taking place at Lexington. The first shots of the American Revolution had been fired; the first blood had been shed. It was about four o'clock when the marching troops came within sight of the town. Until now they had supposed that their secret was safe, and that they would take the patriots off their guard. But the sound of bells, clashing through the morning air, told a different tale. In some way the people had been aroused. Colonel Smith halted his men, sent a messenger to Boston for re-enforcements, and ordered Major Pitcairn, with six companies, to press on to Concord with all haste and secure the bridges. News that the troops were at hand quickly reached Lexington. The drums were beaten, the minute-men gathered, and as the coming morning showed its first gray tinge in the east, it gave light to a new spectacle on Lexington green, that of a force of about a hundred armed militiamen facing five or six times their number of scarlet-coated British troops. It was a critical moment. Neither party wished to fire. Both knew well what the first shot involved. But the moment of prudence did not last. Pitcairn galloped forward, sword in hand, followed quickly by his men, and shouted in ringing tones,-- "Disperse, you villains! Lay down your arms, you rebels, and disperse!"
