General Frederick Steele led a Union army from Little Rock on March 23, 1864, to join an invasion of Texas. Confederate skirmishers harassed the army as it reached Rockport March 27. An inflatable pontoon bridge, in 34 wagons and served by men of the 24th Missouri and 4th Arkansas (African Descent) Infantry, was deployed to help the troops cross the Ouachita one-half mile from here. The Federals again used the bridge to cross the Little Missouri River at Elkins’ Ferry 13 days later. Critically low on supplies, Steele turned to Camden, arriving April 15. After occupying Camden, the Union army used the pontoon bridge to span the Ouachita and ease access to the U.S. troops at Pine Bluff and Little Rock. After suffering severe losses at Poison Spring and Marks’ Mills, Steele abandoned Camden, taking the bridge up and rushing it forward to span the flooded Saline River at Jenkins’ Ferry on April 30. After a savage battle, the Union army crossed. The much-used bridge was in poor condition and the starving mules too weak to pull the wagons, so the Federals destroyed it to prevent its use by Confederate forces.
