In the rolling, ravine-cut, heavy-timbered country near Port Hudson, Louisiana Gen Banks’ Federal army of about 13,000 effectives, made its first assault on the estimated 4500 Confederates under Maj Gen Franklin Gardner (

But the disjointed movements failed along the entire lines, with heavy losses. Federal casualties were 293 killed, 1545 wounded, and 157 missing for a total of 1995. Confederate killed and wounded together were about 235. Assaults on fortified Confederate areas had again proved costly (

In the Vicksburg theater Confederates attacked Union gunboats near Greenwood, Mississippi and skirmished near Lake Providence, Louisiana. On the Mississippi River itself Gen Sherman decided to attempt to reduce a Confederate strong point, Fort Hill, with the aid of the gunboats. U.S.S. Cincinnati, commanded by Lieutenant Bache, ". . . in accordance with Generals Grant's and Sherman's urgent request," moved to enfilade some rifle pits which had barred the Army's progress before Vicksburg. Though Porter took great precautions for the ship's safety by packing her with logs and hay, a shot entered Cincinnati's magazine, "and she commenced filling rapidly." Bache reported: "Before and after this time the enemy fired with great accuracy, hitting us almost every time. We were especially annoyed by plunging shots from the hills, an 8-inch rifle and a 10-inch smoothbore doing us much damage. The shots went entirely through our protection--hay, wood, and iron." Cincinnati, suffering 25 killed or wounded and 15 probable drownings, went down with her colors nailed to the mast. General Sherman wrote: "The style in which the Cincinnati engaged the battery elicited universal praise." And Secretary Welles expressed "the Department's appreciation of your brave conduct."
A Federal scout moved from Memphis toward Hernando, Mississippi and May 27-28 a Federal reconnaissance operated from Murfreesboro on the Manchester Pike in Tennessee. In Virginia Federals scouted May 27-28 from Snicker’s Ferry to Aldie, Fairfax Court House, and Leesburg. William Dorsey Pender, CSA, was appointed to Major General and Edward Payson Chapin, USA, to Brigadier General.
An anxious President Lincoln wired Hooker at the Rappahannock, “what news?” and to Rosecrans at Murfreesboro, “Have you any thing from Grant? Where is Forrest’s Head-Quarters?”
C.S.S. Chattahoochee, commanded by Lieutenant John J. Guthrie, was accidentally sunk with what one Southern newspaper termed "terrible loss of life" by an explosion in her boilers. Occurring while the gunboat was at anchor in the Chattahoochee River, Georgia, the accident cost the lives of some 18 men and injured others. She was later raised but never put to sea and was ultimately destroyed at war's end by the Confederates.
U.S.S. Coeur de Lion, commanded by Acting Master William G. Morris, burned schooners Charity, Gazelle, and Flight in the Yeocomico River, Virginia.
U.S.S. Brooklyn, under Commodore H. H. Bell, captured sloop Blazer with cargo of cotton at Pass Cavallo, Texas.
