On the 13th of October, martial law was proclaimed throughout the county of Surrey (except the county and city of Kingston), and Major-General O'Connor immediately took steps to hem in the disturbed districts. On the 15th of October, a detachment of the 1st West India Regiment was sent to Port Antonio; and at mid-day, Captain Hole, of the 6th Regiment, with 40 men of his own corps, and 60 of the 1st West India Regiment, under Ensign Cullen, marched from that place to Manchioneal, twenty miles eastward of Port Antonio. On the same day, 120 men of the 6th Regiment, under Colonel Hobbs, occupied (as head-quarters) Monklands, in the district of the Blue Mountain Valley, about sixteen miles from Morant Bay. Captain Strachan's company of the 1st West India Regiment proceeded to Spanish Town, whence Lieutenant Allinson, with 31 men, was sent on to Linstead, where a repetition of the Morant Bay massacre was apprehended. A detachment of the 6th was sent to Buff Bay to protect some valuable sugar estates. On the 13th and two succeeding days the insurgents continued their course through Port Morant northward to Manchioneal, and on to Mulatto River and Elmwood; the last of which places is situated in the most northerly part of St. Thomas-in-the-East, where that parish abuts upon Portland. As they advanced with the cry of "colour for colour" they were joined by a considerable number of negroes, who readily assisted in the work of plundering. The houses and stores were sacked. The intention also of taking the lives of the whites was openly avowed, and diligent search was made for particular individuals. But in each case the imperilled person had timely notice, and sought safety in flight. Elmwood was the point furthest from Morant Bay to which the disturbances extended; the arrival of the troops at Port Antonio, on the 15th, putting a stop to the further progress of the insurgents northwards. Thus in the course of four days the rebels had spread over a tract of country extending from White Horses, a few miles to the west of Morant Bay, to Elmwood, at a distance of upwards of thirty miles to the north-east of that place.
