The outfit was composed of a commander and eleven men with horses, arms, and necessary equipment. The Rangers had orders from the Jamestown government to "seize any Indian or Indians whatsoever," and have him, or them, put in jail to remain there until "delivered by due process of law."
Indians were not the only public enemies in the frontier country. In 1698, the gentlemen of Stafford sent a letter of "grievances" to Jamestown asking that the "bloody villain, Squire Tom, a convict upon record," be demanded from the "Emperor of Piscataway," who was then protecting him from punishment.
The activities of the Potomac Rangers are described in a quaint journal kept by one of the Rangers in 1692:
"A Journiall of our Ranging. Given by me, David Strahan, Lieutenant of ye Rangers of Pottomack. June the 17th; We ranged over Ackoquane, and so we Ranged Round persi-Neck and ther we lay that night. And on ye 18th came to Pohike, and ther we heard that Capt. Mason's Servt-man was missing. Then we went to see if we could find him, and we followed his foot abut a mile, to a house that is deserted, and we took ye tract of a great many Indians and we followed it about 10 miles, and having no provisions we was forced to return. June 26th: We Ranged up to Jonathan Matthews hs. along with Capt. Masone, and ther we met with Capt. Houseley, and we sent over for the Emperor, but he would not come, and we went over to ye towne, and they held a Masocomacko and ordered 20 of their Indians to goe after ye Indians that carried away Capt.
