When word came that the invaders had crossed the Utah line, Brigham sent forward a copy of his proclamation and a friendly note of warning to the officer in command. In this he directed that officer to retire from the Territory by the same route he had entered it; adding, however, “should you deem this impracticable and prefer to remain until spring in the vicinity of your present position at Black’s Fork or Green River, you can do so in peace and unmolested on condition that you deposit your arms and ammunition with Lewis Robinson, Quartermaster-General of the Territory, and leave as soon in the spring as the roads will permit you to march. And should you fall short of provisions they will be furnished you upon making the proper application.” The officer who received this note had replied somewhat curtly that the forces he commanded were in Utah by order of the President of the United States and that their future movements would depend wholly upon orders issued by competent military authority. Thus the issue was forced. In addition to the defense of Echo Cañon, certain aggressive moves were made. To Joel Rae was allotted command of one of these. His orders promised all he could wish of action. He read them and felt something like his old truculent enthusiasm. “You will proceed with all possible dispatch, without injuring your animals, to the Oregon Road near the bend of Bear River, north by east of this place. When you approach the road, send scouts ahead to ascertain if the invading troops have passed that way. Should they have passed, take a concealed route and get ahead of them. On ascertaining the locality of the troops, proceed at once to annoy them in every possible way. Use every exertion to stampede their animals and set fire to their trains. Burn the whole country before them and on their flanks. Keep them from sleeping, by night surprises; blockade the road by felling trees, or destroying river fords where you can. Watch for opportunities to set fire to the grass on their windward, so as to envelope their trains if possible. Leave no grass before them that can be burned. Keep your men concealed as much as possible, and guard against surprise. God bless you and give you success. “YOUR BROTHER IN CHRIST.” Forty-four men were placed under his command to perform this work, and all of them were soon impressed, even to alarm, by the very evident reliance of their leader upon the God of Israel rather than upon any merely human wisdom of his own. The first capture was not difficult. After an all-night ride they came up with a supply-train of twenty-five wagons drawn by oxen. The captain of this train was ordered to “go the other way” until he reached the States. He started; but as he retraced his steps as often as they moved away, they at length burned his train and left him.
