Eventually, the Covenanters took the city of Newcastle upon Tyne by storm, and the Royalist garrison who still held castle keep surrendered on terms.

As Leslie moved his army south he left six regiments under the direction of Lieutenant General James Livingstone, 1st Earl of Callander, to lay siege to the city of Newcastle upon Tyne beginning 3 February (after the town was formally asked to surrender).

In a complicated situation, the Earl of Callander diverted his troops to take surrounding towns like Newburn, as the main Covenanter army pressed south.

Finding the situation hopeless, surrender was negotiated with General Leslie by the Royalist Governor, Sir John Marlay on 27 October 1644.

Tynemouth had fallen on 27 October 1644 and the Scots were now able to control the Tyneside coal trade for a second time which they did until they were persuaded to leave on 30 January 1647 with the demise of the Solemn League and Covenant.
