Detailed Port Hudson Battlefield map - Assaults of May 27, 1863

This very detailed map shows topographical features as well as locations of Confederate defensive positions and their commanders, and the Union forces and their commanders which attacked on May 27th. Battles raged all along the Confederate lines, with primary assaults being made by Generals Weitzel and Grover on the northeastern Confederate defenses known as Commissary Hill, Fort Babcock, The Bullpen, and Fort Desperate, while Auger attacked the Confederate center, and Sherman's men attacked across Slaughter's Field. General Dwight's black troops of the 1st and 3rd Louisiana Native Guard regiments attacked the northwest corner of the Confederate lines. None of these thrusts resulted in any significant penetration of the defenses.
