 These reinforcements enabled the Union to win the next day's Battle of Pleasant Hill, but Banks immediately ordered a retreat to Grand Ecore, and from there, to Alexandria.During this retreat, the regiment fought rear guard actions at Natchitoches, Monett's Ferry, and Cloutierville.After Smith's forces arrived in Alexandria on April 26, they were temporarily deployed to prevent attacks during Joseph Bailey's attempts to get Porter's squadron over the rapids there, with the aid of Bailey's Dam and two small wing dams upstream.
