Cromwell took the field at the end of June, intent on bringing Leslie to
battle. First, however, he resumed his attempt to gain control of Fife, ‘the
breadbasket of Scotland’, which he had had to abandon in February. He now
made use of fifty flat-bottomed boats, which he had then ordered to be built,
in order to transport 4,000 men under Major-General Overton (as he now
was) across the Firth of Forth, with orders to secure and fortify the penin-
sula between that water and the Firth of Tay. Leslie, whose immediate aim
was to protect Stirling, had taken up a strong defensive position at Torwood,
six miles down the Stirling–Edinburgh road. To distract attention from Over-
ton’s operation, Cromwell marched against Leslie and took up battle stations
opposite his defences, challenging him to come out and fight. When that
failed to draw him, Cromwell moved west to Glasgow and conducted forays
into the territory in which the Scots were busy recruiting. This brought Leslie
westward to Kilsyth on 13 July, and focused his whole attention on Cromwell
during the next week, while the flatboats ferried the English forces over the
Forth to North Queensferry. Cromwell entrusted the operation to Lambert,
now promoted to Lieutenant-General. Leslie heard of it just too late, but sent
Major-General Holborne with over 4,000 men to oppose it. Lambert imme-
diately forced a battle at Inverkeithing, only a mile or so from where he had just
landed. After some preliminary skirmishing the battle proper lasted just a
quarter of an hour, and for the Scots it was an utter rout. Their cavalry were
put to flight and their infantry, mostly Highland clansmen, were cut down
where they stood. About 2,000 men were killed and 1,400 captured; perhaps
1,000 got back to Stirling.

Cromwell thereupon brought his own forces back to Edinburgh and Leith,
and then transported the greater part of them into Fife. He next marched not
against Stirling, Leslie’s headquarters, but against Perth, the current seat of
Scottish government, far to the north-west. After Inverkeithing Leslie’s
demoralized men were deserting in droves, and Cromwell was deliberately
leaving the way open for them to invade England. Confident now of complete
military superiority, he was content to take the risk of fighting the decisive
battle on English soil. Charles and Leslie realized that for them the risk was
even greater. Argyll and Loudoun thought that invasion would be madness,
and washed their hands of it. But Charles feared that if he stayed in Scotland
and suffered military defeat there, as was now almost inevitable, he would
become the prisoner of the Kirk party again. So he and his army set off south-
ward from Stirling on 31 July, two days before Perth surrendered to
Cromwell, as usual on generous terms. He and Leslie had little more than
12,000 men with them, and they were so short of firearms that fifty or sixty
