John Porteous having been for some time in the army, and being known to be possessed of no small courage and daring, was selected by John Campbell, lord provost of Edinburgh, in the memorable year 1715, to be drill-sergeant of the city-guard, as it became necessary to have the guard well disciplined and made as effective as possible in that eventful period, for the support of the government and the protection of Edinburgh. In this office he discharged his duty remarkably well, and was often sent for by the lord provost to report what progress his men made in military discipline. This gave him an opportunity of meeting sometimes with a gentlewoman who had the charge of the lord provost's house and family, with whom he fell deeply in love; after paying his addresses for some time, and proposing to her, he was accepted, and they were married. From a grateful sense of her services, as well as from a conviction of Porteous's ability for the office, the lord provost proposed that John Porteous should be elected one of the captains of the city-guard, and it was agreed to. This was a situation of trust and respectability, and would have enabled the young couple to live in comfort and ease if the husband had conducted himself properly. The gentlewoman was a person of virtue and merit, but was unlucky in her choice of a husband--Porteous was no better a husband than he had been a son. They were not long married when he began to ill-use her. He dragged her out of bed by the hair of the head, and beat her to the effusion of blood. The whole neighbourhood were alarmed sometimes at midnight by her shrieks and cries; so much so, indeed, that a lady living above them was obliged, between terms, to take a lodging elsewhere for her own quiet. Mrs Porteous was obliged to separate from her husband, and this was her requital for having been the occasion of his advancement. His command of the city-guard gave him great opportunities of displaying his evil temper, and manifesting his ungovernable passions. Seldom a day passed but some of his men experienced his severity. The mob on all public occasions excited his naturally bad temper; and on all days of rejoicing, when there was a multitude from the country as well as from the town, the people were sure to experience offensive and tyrannical treatment from him. The hatred and terror of him increased every year, and his character as an immoral man was known to everybody, so that he was universally hated and feared by the lower orders both in town and country. This was the position in which Captain Porteous stood with the people when he was called upon to take charge of the execution of the law in reference to Andrew Wilson, whose case it has been thought proper to detail before proceeding to narrate the extraordinary events that followed, and which, indeed, partly serves to explain the cause of these events.
