Engagement at Campbell’s Island

The engagement at Campbell’s Island on 19 July 1814 was one of several American failures on the upper Mississippi during the summer of 1814. A small gunboat expedition ascending the river toward Prairie du Chien was attacked by Sauk warriors and forced to retreat with significant casualties — another demonstration that British-Indigenous control of the upper Mississippi corridor was unchallenged by anything the Americans could deploy.

Lieutenant John Campbell (for whom the island was later named) commanded three gunboats carrying approximately 120 men upriver. The expedition’s objective was to reinforce or recapture the American positions on the upper Mississippi that had been falling to British-Indigenous forces throughout the summer.

At an island near the mouth of the Rock River (present-day Rock Island, Illinois), the gunboats were attacked by approximately 400 Sauk warriors firing from the riverbanks and from canoes. A British gunboat with a small regular detachment provided additional firepower. The Americans were caught in a crossfire — unable to bring their guns to bear effectively against opponents concealed on both banks.

The engagement lasted several hours. Two of Campbell’s three gunboats were forced to withdraw downriver, their crews suffering 16 killed and approximately 20 wounded. The third gunboat was grounded and its crew evacuated under fire. Campbell himself was wounded.

The failure at Campbell’s Island, combined with Zachary Taylor’s defeat at Credit Island two days later and the capture of Prairie du Chien, confirmed that the upper Mississippi was beyond American military reach. British influence, exercised through the fur trade network and the Indigenous alliances it sustained, extended deep into the continental interior — a reach that American arms could not contest.
