John Henry Bastide, a subaltern in Montague's regiment who had a long career as a military engineer drew a detailed plan of the battlefield and the movements of the opposing forces soon after the battle.
The section detailing the battle itself is missing but it is possible to reconstruct the main elements.

Tullibardine prepared a strong position near the Five Sisters hills, with the Spanish in the centre and the Highlanders on the flanks behind a series of trenches and barricades.
Wightman's force arrived about 4:00 pm on 10 June and began the attack an hour later by firing their mortars at the Jacobite flanking positions.
This caused few casualties but the Scots had not encountered mortars before, allowing four platoons of Clayton's and Munro's to advance up the hill to their lines, then use grenades to bomb them out of their positions.

Once the Jacobite right had been dislodged, Harrison and Montague attacked the Jacobite left under Lord Seaforth.
This was strongly entrenched behind a group of rocks on the hillside but skilful use of the mortars forced Seaforth's men to give way while he himself was badly wounded.
Commanded by Colonel Nicolas de Castro Bolano, the Spanish in the centre stood their ground, but had to withdraw up the mountain as their flanks gave way.

The battle lasted until 9:00 pm; several accounts claim the heather caught fire and smoke combined with failing light enabled the bulk of the Scots to disappear into the night.
The Spanish surrendered next morning, and as regular troops were later shipped home; Lord George Murray, Seaforth and Tullibardine were wounded but the Jacobite leaders also managed to escape.
An analysis by historian Peter Simpson attributes Wightman's victory to skilful use of mortars, the superior firepower of his grenadiers and the aggression shown by his infantry.
