|Before proceeding, it may be necessary briefly to explain what the brigadier had accomplished since he quitted Perth about ten days previously. At that time, the detachment under his command consisted of six regiments, and with a number of gentlemen volunteers formed a total of two thousand five hundred men. The brigadier's orders from the Earl of Mar were to get as many men as he could over the Firth, and though the channel was defended by ships of war, smacks, and boats filled with armed men, Mackintosh courageously made the attempt, and despite all the exertions of the cruisers to prevent him, succeeded in reaching the East Lothian coast with fifteen hundred men--the Earl of Strathmore's battalion being forced back and compelled to go on shore on the Isle of May. This was the exploit to which Lord Kenmure had referred in terms of such high admiration. With the troops he had thus brought across the Firth, the brigadier at once marched to Haddington, where he was invited by the Scottish Jacobites to make an attempt on Edinburgh, and unhesitatingly complied with the request. He advanced as far as Jock's Lodge, but not meeting with the promised support, he turned to Leith, and took possession of a partly-demolished fort, built by Oliver Cromwell, and proceeded to barricade it. Next day the Duke of Argyle, who had hastened from Stirling to the protection of Edinburgh, summoned him to surrender. On his refusal, the duke threatened to bombard the fort on the morrow, but in the night Mackintosh withdrew, and conducted his men cautiously along the sands at low water to Seaton House--a castle belonging to Lord Wintoun. Here he posted himself securely with his force, and laughed at the threats of Lord Torpichen and the Earl of Rothes, who came from Edinburgh to dislodge him with two hundred dragoons and three hundred volunteers. At Seaton House he remained fora couple of days, and in that short interval stored it with provisions to stand a siege, when he learnt that the South Country Scots and Northumbrians had risen, and received an express from Forster praying him to meet him at Coldstream or Kelso. Another express came from the Earl of Mar bidding him march south, and join the English insurgents. The latter order could not be disobeyed, and he therefore quitted the stronghold he had gained, and marched to Longformacus, harassed in the rear by the Government troops. But this pursuit did not prevent him from plundering the house of Doctor Sinclair, who had incurred the animosity of the Jacobites by shooting young Hepburn of Keith. Continuing his march to Dunse, the brigadier rested there for a day, proclaimed James the Third, collected the excise dues, and received the very satisfactory intelligence that Sir William Bennet had abandoned Kelso. No longer troubled by the Government troops, and renovated by the much-needed repose, he marched on next day to Kelso, and was met at Ednam Bridge, as we have related, by the Lowlanders.
