On the evening of Monday, being the fifth current, several soldiers of the 29th Regiment were seen parading the streets with their drawn cutlasses and bayonets, abusing and wounding numbers of the inhabitants.

A few minutes after nine o'clock four youths, named Edward Archbald, William Merchant, Francis Archbald, and John Leech, jun., came down Cornhill together, and separating at Doctor Loring's corner, the two former were passing the narrow alley leading to Murray's barrack in which was a soldier brandishing a broad sword of an uncommon size against the walls, out of which he struck fire plentifully. A person of mean countenance armed with a large cudgel bore him company. Edward Archbald admonished Mr. Merchant to take care of the sword, on which the soldier turned round and struck Archbald on the arm, then pushed at Merchant and pierced through his clothes inside the arm close to the armpit and grazed the skin. Merchant then struck the soldier with a short stick he had; and the other person ran to the barrack and brought with him two soldiers, one armed with a pair of tongs, the other with a shovel. He with the tongs pursued Archbald back through the alley, collared and laid him over the head with the tongs. The noise brought people together; and John Hicks, a young lad, coming up, knocked the soldier down but let him get up again; and more lads gathering, drove them back to the barrack where the boys stood some time as it were to keep them in. In less than a minute ten or twelve of them came out with drawn cutlasses, clubs, and bayonets and set upon the unarmed boys and young folk who stood them a little while but, finding the inequality of their equipment, dispersed. On hearing the noise, one Samuel Atwood came up to see what was the matter; and entering the alley from dock square, heard the latter part of the combat; and when the boys had dispersed he met the ten or twelve soldiers aforesaid rushing down the alley towards the square and asked them if they intended to murder people? They answered Yes, by G-d, root and branch! With that one of them struck Mr. Atwood with a club which was repeated by another; and being unarmed, he turned to go off and received a wound on the left shoulder which reached the bone and gave him much pain. Retreating a few steps, Mr. Atwood met two officers and said, gentlemen, what is the matter? They answered, you'll see by and by. Immediately after, those heroes appeared in the square, asking where were the boogers? where were the cowards? But notwithstanding their fierceness to naked men, one of them advanced towards a youth who had a split of a raw stave in his hand and said, damn them, here is one of them. But the young man seeing a person near him with a drawn sword and good cane ready to support him, held up his stave in defiance; and they quietly passed by him up the little alley by Mr. Silsby's to King Street where they attacked single and unarmed persons till they raised much clamour, and then turned down Cornhill Street, insulting all they met in like manner and pursuing some to their very doors. Thirty or forty persons, mostly lads, being by this means gathered in King Street, Capt. Preston with a party of men with charged bayonets, came from the main guard to the commissioner's house, the soldiers pushing their bayonets, crying, make way! They took place by the custom house and, continuing to push to drive the people off, pricked some in several places, on which they were clamorous and, it is said, threw snow balls. On this, the Captain commanded them to fire; and more snow balls coming, he again said, damn you, fire, be the consequence what it will! One soldier then fired, and a townsman with a cudgel struck him over the hands with such force that he dropped his firelock; and, rushing forward, aimed a blow at the Captain's head which grazed his hat and fell pretty heavy upon his arm. However, the soldiers continued the fire successively till seven or eight or, as some say, eleven guns were discharged.
