[5] Munro grew up a bold, powerful and fearless man, playing a conspicuous part in the history and feuds of his time.

[7] The petty differences on the part of those in command led to no properly defined plan of attack and George Munro was so disgusted with these matters that he returned home to Scotland.

[7] Munro fought in the Irish Confederate Wars under his uncle Robert Monro who commanded the Scottish Covenanter army.

[8] Between 1642 and 1646 George and his uncle Robert were generally successful against their enemies the O'Neils, and during that time the Munros put down a rebellion in Ulster in 1642 and captured Belfast in 1644.

[7] General Robert Monro was defeated by the Irish Confederates at the Battle of Benburb in Ireland in 1646 and Carrickfergus Castle was surrendered to the English Parliamentarian George Monck in 1648.

[10] These, with the accessions of forces which were daily arriving from different parts of the kingdom, were quite sufficient to have put down the insurrection in the west; but instead of marching, Lanark, to everyone's surprise, proceeded through East Lothian towards the eastern borders to meet up with Sir George Munro, who was retiring upon Berwick before the army of Cromwell.

[10] The Earl of Lanark declined to attack Covenanter David Leslie, Lord Newark, acting contrary to the advice of George Munro and his other officers.

[10] This success was reported to the Earl of Lanark, and it was represented to him that by following it up immediately, while the enemy continued in the state of alarm, he might perhaps obtain a bloodless victory, secure possession of the city of Edinburgh and the town of Leith.

[10] Ever since the Earl of Lanark's march to the borders to meet Munro, Archibald Campbell, 1st Marquess of Argyll had been busily employed in raising men in his own territory to assist the Covenanters.

[16] The siege of Derry however was not successful and Munro was forced into a final return to Scotland in April 1650 as a result of the rout of the Scottish royalist army at the Battle of Lisnagarvey.

The royalist uprising, led by William Cunningham, 9th Earl of Glencairn in support of the exiled King Charles II, began in 1651.
