Soon after the arrival of Paul Revere between 12 and 1 o'clock in the morning of April 19, with the intelligence of the starting of the King's troops, Captain Parker assembled his company on the Common. The roll was called and they were instructed to load with powder and ball. One of the messengers who had been sent towards Boston, returned and reported that he could not discover any troops on the way out, which raised some doubts as to their coming. It was between 1 and 2 o'clock when they were dismissed with instructions, however, to remain in the immediate neighborhood, for quick response to the call of the drum. Many of them adjourned to Buckman's Tavern, and the others, living in the immediate vicinity, returned to their homes.

Between daylight and sunrise Capt. Thaddeus Bowman rode up, and reported that the regulars were near. The drum was beat, and Captain Parker's little band assembled on the Common.

The soldiers of the King were but one hundred rods down the road.[71]

Bedford an adjoining town to Lexington, and about fifteen miles from Boston, was alarmed on the evening of the 18th, by Nathan Munroe and Benjamin Tidd, both of Lexington, who had been sent there by Captain Parker because of the suspicious actions of the British officers on their way to Concord. Munroe and Tidd aroused the town, and some of the minute-men rallied at the tavern kept by Nathan Fitch, Jr., and were there served with light refreshments. Captain Willson said:—

"It is a cold breakfast, boys, but we will give the British a hot dinner. We'll have every dog of them before night."[72]

The larger Bedford rally was at the oak tree standing in the little triangle a few rods west of the village, where the road to Concord branches away from the road to Billerica.[73]

Munroe and Tidd continued their alarm to Meriam's Corner in Concord and returned to Lexington in time to hear the first alarm bell in the morning of the 19th, and witness the assembling of Capt. Parker's Company. Munroe, being a member joined the ranks, and Tidd remained on or near the Common and was dispersed with the rest.[74]

Josiah Nelson, living in the northeast part of Lincoln, was awakened on the night of the 18th, by horsemen passing up the road. Rushing out partly dressed, to ascertain who they were, he received a blow on his head from a sword, cutting sufficiently to draw the blood. He was seized and detained a little while by his British captors, and when released had his wound dressed, and hurried to Bedford and gave the alarm in that town also.[75]

Billerica, seventeen miles northwest from Boston, probably received the alarm about two o'clock, and when the encounter on Lexington Common took place few if any families but had heard the call to arms.[76]
