night. April 9 saw Taylor attack Banks again, in the Battle of Pleasant Hill. The Confederate attacks at Pleasant Hill were blunted, and while modern historians usually consider Pleasant Hill a Union victory, Banks continued to retreat. The Union forces continued to withdraw, pursued by some of Taylor's men, but Banks's army and Porter's fleet were able to escape. The Red River campaign was a Union failure and prevented the Union from sending troops to other regions, and postponed a planned assault on Mobile, Alabama, which in turned freed up other Confederate troops. The Camden expedition likewise ended in failure. Park history In 1924, of the battlefield were donated to the United Daughters of the Confederacy (UDC) for a memorial park. The next year, a monument to the Prince de Polignac, a Confederate officer, was erected at the site. This was the first monument at the site. That same year, state congressman W. H. Farmer introduced legislation to provide $5,000 of state funds for the site. Governor of Louisiana Henry L. Fuqua signed Farmer's bill into law in July. In 1928, work on a $1,000 archway at the park was begun. By 1929, the site had become a place for local youth to go and engage in petting. The Works Progress Administration performed work at the site in 1936 and 1937. In 1939, ceremonies, including a luncheon and a tree-planting, were held at the park for the 75th anniversary of the battle. 1954 saw maintenance of the site transfers from the UDC to the Louisiana state government. By that time, the UDC had expanded the park to , and three additional monuments (to Taylor and two Confederate officers killed in the battle) had been placed. Funding issues had resulted in the UDC being unable to provide their desired level of maintenance, and attempts to make the site a national park had failed. The state allocated additional funds for a museum, and surveying for the museum site began the next year. The museum was dedicated in 1957. In 1964, festivities, to involve people from both Louisiana and Texas, were planned for the 100th anniversary of the battle. That same year, another marker, this one honoring Texas troops who fought in the battle, was erected at the site. In 1972, a scale model of a monument at Gettysburg National Military Park commemorating Louisiana Confederate soldiers was erected at the Mansfield park. On
