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.
