Battle of Chalk Bluff

Marmaduke departed his camps in Arkansas in the spring of 1863 with 5,000 cavalrymen, bound for southeastern Missouri. In sharp fighting at the Battle of Cape Girardeau, Marmaduke was defeated, and he began a withdrawal on April 27 towards Helena, Arkansas. His line of march was on a road on Crowley's Ridge, a long rise that offered protection for his flanks, as the surrounding terrain was mainly marshy. Union forces under Vandever had pursued Marmaduke through Missouri to Chalk Bluff, Arkansas, where Marmaduke planned to cross the St. Francis River, whose steep chalky white clay banks made fording the river difficult for cavalry.

In an attempt to protect his men while they were crossing the river, Marmaduke set up a rear guard along the ridge that he hoped would protect his engineers and pioneers as they constructed a bridge strong enough to allow the passage of his entire division. He formed an initial defensive line at the hamlet of Four Mile, while posting his reserves in a second line a mile away at Gravel Hill, on the crest of the ridge above the river. They began digging entrenchments to forestall any Union attack.

Fighting began on May 1 and continued into the next day. Vandever's men were unable to drive the Confederates from the heights. Although Marmaduke's rear guard sustained heavy casualties, it delayed the numerically superior Union forces long enough as to allow for the construction team to finish building the bridge and allow Marmaduke’s main force to cross the river. However, because of the heavy casualties that were suffered by the Confederates, Marmaduke was forced to end the expedition and return to his camp.

While, in some respects, Marmaduke tactically won the Battle of Chalk Bluff, the Union forces claimed a strategic victory since he had abandoned his spring offensive.

The battle is commemorated today in the small Chalk Bluff Battlefield Park, which preserves a portion of the field and has been listed on the National Register of Historic Places. The Chalk Bluff Hiking Trail traverses parts of the battlefield, with interpretive wayside markers and panels. A few minor skirmishes occurred there later in the war as both armies sent raiding parties to control the river crossing.

The towns of Chalk Bluff, Four Mile and Gravel Hill are no longer extant.
