Mcclellan's Generalship--an Abolition Witness

We give belüw a letter froin Samuel Wilkeson, one of iho editors of the New York Tribune. It was written, as our readers will see, od the field, and 'tho writer knew of what ta spoke. Mr. Wilkeson i neither the personal uor politioal partisau of General McCleilau, but ou tho contrary ranks as a most ardent Radical Republican, and a journalist of tho highest standing. What ha wrote from the White Oak Swamp ia June, 1862, stands as bis convicción today. Not a word or syllable has he ever uttered to modify or tone dov" tha burning indignation of this language : OS THE MARCII THKOUGH THE WüITE ) Oak Swámp, June 28, 1863. f Outuuuibered, surroundod, . liable at any moment to be cut off from our base of supplies, and to have our possessiou of the York River Railrotd wrenclied, from our gfasp, McOlellaa came out at star rising from the fi?ht in which ho had shared the perils of a commou soldier, with a Napoleonic coneeption of tha only salvation for his anny froiu lation by fire, or loss by capture. He ordered new roadá to be instantly cut through the swanip that separate ua from the Charles óity highway; and commuuicated to his Generala hi purpose to change his baae by a rapid movement to James river. We uiarch now through White Oak Swamp, to chaage n twelve hour's time, the base of a great ariny - doomod where it was, and haviug uow but little graoe or delay accorded to it by an aotivo and brave euetny, numerous enough to encircle us at auy poiot, aud to outnumber ua at all The movement is bold, soldierlike and brilliant, but etninently hazardous. It is made by the üght ot tha burning of every one of the bridgen, whieh we have so painfully thrown over the Chickahominy, and withia hearing of the destruction, by our own hands, of the railroad whieh gave us our gupplies, and was to secure us retreat. The move ment will nrobablv be suceassful. thoush its trail will bo bloody. The world will regard it as a masterly stroke of geniui, Tho arrny will so regard it, and will feel ior its comraander the admiration and gratitude that saviors of mea ever enkiadle in loyal liearls But the brilliancy of this movemcnt will not for an instant dazzle tbe eyes of the vvrongod and wrathful men of' the Army of the Potomac, nor will it dazzle the sight of the angry people so as for a moment to obscure ther pereeption of the crime against the nation, which has made this change of base and front imperiousfy neceisary. Tuu ciume is the kefusaj, TO REINFORCE McCtEIAAN. I dotl't care about tho question - which legisla tors, soldiers and politicians have da bated - of this General's fitness to command. Tho York and James River Península waa not the place ior that discu-sion. The hour of tho iuuetioa of Beauregard's and Jaokson's forcea to those of Johnstou, is not the time for sueh a debato. I eare not for any criticism of Gen. MeClellan'a campaign on this Peni.isula, or on the Potomac. I have blows, but not a word, for the tm-. timely eausiat, in or out of administrativa offico, who, under the roar of rebel canuon, sweepiug our rauks witb. shot and ghell, meets the demanda for aid to this army with a ohronological meaaure of delays at Port Mooroe, at Yorktowa, at Williamsburg, at Keven Pines. I don't care whether they were delays or lo delays - ivbetber they were MeClellan'a delays, the Quarteruiastor General'a dalays, or the delays of the elemente 1 No man, no party, and uo interest, shall with my assont, or my silence, be permitted to mix up with the sacred right of aa outnumberod American army to demand help from their countrymen, and to proroptly feoeive it, collateral uestious of fitness, of vigor, of fidelity. Ahon loyal New York regiments, lifted rom their feet by tbe fire of rebel brigidee, ory out oí' their wounds and death br help - whon the choicest of New Sngland, and Michigan, aud Pennsylvaiia troop, outnumbered in front and on joth flauka by wholo divisions of the :nemy, beg for reinforcements. I say hat the blaokest crimu that Power can joimnit is tü stalk upou the fidld of peril ind say : Soldiers 1 have oo faith in yonr commander, let your martyrdom procoed. And so saya this Army oí the Potoraao. Aud it register-i to night vows of vengöance as it marches in the dark from a position which thuir diminiáhed numbers disabled them from holding, but which ia cousecratod to them forever by their Bufferings, their labora riDd their wrongn. The polittcian and siatesmen who lejt us here to be outnumbered and cut off from our supplies, and the possibility of retreat are doomed men. 8. W. lu view of this statemeut from one of the most promiuunt jouroala of the day, and oue of thoir ovni sido too, we cannot me how abalitionisl.s ean persist in their abu-e of that General.
