The rebellion was followed by strong measures being taken against Roman Catholics, as it gave another pretext for the seizing of their estates by the Commissioners, more particularly the properties of those who had died just before the events of 1715; and there is no doubt but that many of their descendants were harshly and unjustly dealt with. The oaths of supremacy and allegiance were now urged upon both clergy and laity, and all Roman Catholics and Nonjurors were compelled to register the value of their estates. The returns made by the Commissioners showed that in Amounderness there were 73 estates, worth per annum £2,260; in Lonsdale, 25, yielding £1,432; in Blackburn, 29, yielding £972; in Leyland, 54, yielding £1,463; in Salford, 17, yielding £721; in West Derby, 122, yielding £5,901. From this return it appears that the yearly value of the Nonjurors' estates (chiefly Roman Catholics) in Derby and Amounderness was nearly twice as much as all the rest of the county put together; and the numbers of estates in these two hundreds, though not quite in the same proportion, was very much greater than that in the other parts of Lancashire. Shortly after the events just narrated, a strong controversy arose in Lancashire and other parts of the kingdom as to what was spoken of as the _Divine right of kings_, the Nonjurors maintaining that no circumstances whatever could justify an insurrection against the King, and therefore no one but a descendant of James II. could claim from them an oath of allegiance. The holders of this doctrine were plentiful in Lancashire, and in Manchester particularly, and there were many who at once espoused the cause of Prince Charles Edward (the son of the Pretender), when in August, 1745, he landed in the Hebrides on his way, as he fondly hoped, to the throne. On November 16 following, the Young Chevalier, with a small army, got possession of Carlisle, and was proclaimed King of Great Britain. Leaving Carlisle, the Young Pretender marched through Penrith to Lancaster, where he arrived on November 24, at the head of about 5,000 men, chiefly Highlanders; from thence they passed on to Preston, which was reached on November 27, and by a forced march they arrived at Manchester the following day. Here for the first time during their passage through Lancashire they obtained some substantial assistance, by the addition to their forces of some 200 men, which were placed under the command of Colonel Francis Townley, and were designated the Manchester Regiment. The Jacobites of Manchester received the Prince with public demonstrations of joy. From Manchester the insurgents went to Derby, where they ascertained that they were in danger of being hemmed in by two armies of the Government, and therefore they wisely at once began to retreat, passing again through Manchester, Preston, and Lancaster, and crossed the Scottish Border on the 20th, having marched 200 miles in fourteen days.
