The Expedition to White River.
[Correspondence of the St. Louis Republican.]
Above Helena, Ark. June 16, 1862.

The St. Louis ought to be the pride of St. Louisans, having been built and their city, and having borne their city name with honor worthy the most beautiful flag its fair daughters can make. She went into commission December 14, 1861, and was hence the first iron-clad boat upon the Western waters. She has seen service. Besides the reconnaissance duty, she was in the fight in the bend above Columbus, where she sunk the rebel gunboat Lady Polk; at Fort Henry, where she received sixty-two shots; at Fort Donelson, where she received eighty-four; and she bore her part gallantly in the fight at Island No. 10, Fort Pillow and at Memphis. In truth, no boat has better earned the reputation of a "fighting boat," and no more brave and gentlemanly set of officers ever walk a deck.

As many changes have taken place in the muster roll of the St. Louis since she went into commission, I append a correct list of her gallant officers:
Wilson McGunnegle, Lieutenant Commanding.
John V. Johnson, First Master.
C.H. Kendrick, Second Master.
Alex Fraser, Third Master.
James P. Paulding, Fourth Master.
S. H. MacAdams, Master’s Mate.
W.R. Crocker, Master’s Mate.
Llewellyn Curry, Paymaster, absent.
W.C. Underwood, Pilot.
R.G. Baldwin, Pilot, absent.
William Caswell, Engineer.
T.F. Ackerman, First Assistant Engineer.
James L. Smith, Second Assistant Engineer.
John Wilcoxson, Third Assistant Engineer.
John H. McDonald, Gunner.
R.H. Medill, Carpenter.
A.J. Sypher, Armorer.
D.K. Cone, Paymaster’s Steward.
Park B. Chase, Surgeon’s Steward.

The boats that accompany this expedition are the Mound City, St. Louis, Lexington, Conestoga and two rams, besides one or two transports, with forage, &c.
All along the river to this point nothing has occurred of exciting interest. We expect a “time” at Helena, however. In ascending that the many rivers of the Southwest, in search of rebel craft, we expect to have an exciting time.
In White river, it is said, we shall find the Clara Dolson, Bracelet, W.M. Morrison, E.J. Gay, and several other boats.
The Yazoo is full of them, among which are said to be the Quitman (she was finally saved from her recent grounding), Hartford City, Charm, Ben McCulloch (the gunboat partially built here), and several others.
