 Simcoe's troops were moving down the road toward Williamsburg, convoying some cattle with the infantry and jägers in the lead under Major Richard Armstrong, with Simcoe and the cavalry about an hour behind them. At Spencer's Ordinary ("ordinary" meaning tavern at the time), the troops rejoined and paused to rest. Simcoe ordered fences in the area torn down since "it was an admirable place for the chicanery of action". While they rested, some of the Loyalists went out to round up more cattle found in the area, and the cavalry went to a nearby farm to feed their horses. McPherson's men encountered the latter, whose sentries raised the alarm to the main body. Simcoe's cavalry charged McPherson's formation, breaking it up. McPherson and a number of his men were unhorsed in the melee, and several were taken prisoner before the leading edge of Butler's main force began to arrive. Simcoe ordered most of the infantry up to support his cavalry, and sent the jägers and light infantry into the woods on the right to flank the arriving enemy column. By questioning the prisoners, Simcoe learned that Lafayette was not far off. He sent word to Cornwallis, dispatched the cattle convoy toward Williamsburg, and ordered trees to be felled to make a barricade across the road as a point of defense. He then arrayed his troops in a way calculated to mislead the Americans into believing that more troops were in formation just over a rise. When Butler's force arrived, Simcoe ordered an infantry charge. This scattered the first wave of Butler's men into the nearby woods, where the jägers then pushed them back. However, Butler's men continued to advance. Simcoe ordered a cavalry charge and fired a field cannon to give the impression that a larger force was arriving. The charge forced Butler's men back, at which point the two forces disengaged, Simcoe because he was concerned that Lafayette was approaching, and Butler because his men were fooled by Simcoe's stratagem.
