For all of Alexander Norman’s confidence in the New Model Army, it was a desperate gamble that John was taking with his son’s safety. Sometimes he thought of Charles Stuart and himself, at opposite ends of the country, both taking their desperate gambles – one for the crown of England, one for the life of his son. It did not trouble John that he was gambling on Charles Stuart’s failure. John’s loyalty to the kings, never a strong flame, had flickered fitfully all through the first king’s war, and been blown out altogether when the war had been renewed not once, but twice, after defeat. His vigil at the courtroom and scaffold had been a farewell to a man he had served, not the act of a loyal royalist. John’s sympathies had always been independent, now, a citizen of a republic, he could call himself a republican.

More than anything else he wanted peace, a society in which he could garden, in which he could watch his children grow to adulthood, make marriages and have children of their own. He would have been hard-pressed to forgive any man for breaking the peace of the new state. And Charles Stuart did not sound like an exceptional man. Cromwell himself complained that the prince was so debauched that he would undo the whole country. All the news of the prince’s court over the water had been of popery, folly, and vice.

But it was a close thing. The Scots army first met the English just south of Edinburgh for the battle on Scottish soil that Alexander had predicted. The Scots were in fine form, and filled with confidence at the presence of the young king. The English army were tired from the long march north, and were losing men all the way as individual soldiers changed their minds and turned south for home. The Commander-in-Chief, Cromwell, was in one of his dark moods when he doubted his men’s abilities and, worse than that, doubted his own. The voice of God which guided him so clearly had suddenly gone silent and Cromwell was spiralling down into one of his disabling fits of despair. It was only John Lambert’s unshakable optimism that kept the army marching north.

Then they nearly lost Lambert at the battle of Musselburgh, just south of Edinburgh, when his horse was shot dead under him and Lambert, falling, was lanced in the thigh. The Scots infantry spotted him, and a band of them were dragging him away from the battlefield when his own regiment, Yorkshiremen most of them, let out a yell of horror which made even the Highlanders check, and charged through the crowd to get to him.
