the war thai was coming to his doorstep was one he had Invited by bii action three months earlier at Charleston-There has also been an intelligence myth oo the Federal side.

What Happened

The fact Is that by the time Johnston's rearmost units leftword of the movement had already reached the headquarters ol the Federal oommander in the Valley, Ceneral Patterson. It came through channels operatedvilian member of Patterson'salley native wbo was then and thereafter able to get news, usually via Negro messengers, from Unionists beyond the Confederate lines. But this, his first important report, was not accepted byuntil corroborated (presumably by reconnaissance) two days after Johnston was gone.

During most of those three days McDowell was busylan of attack on tbe basis of reconnaissance which had to be con ducted after be reached BuD Run. His march bad been forced by pressures on the Federal Administration, and among the things be had not had time to get around to before leaving Washington was an adequate intelligence preparation. Later in the war It turned out there had been no lack of Union sympathizers in the locality wbo could have pinpointed In advance the undefended fords McDowell had to find while his army was kept waiting.

Not rairprisingly. tbe war for which each side was ill prepared opened with blundering application of intelligence on both sides. Beauregard's poor use of bis advance information would have earned him defeat had not tbe Federals been busy tccoonotearing up and down Bull Bun for three days, making up their homework. It was at the end of those days that Johnston's troops began arriving at Manassas,

Pinkerton Assessments

The Federal defeat at First Bull Run led directly to the elevation lo high command of Major Ceneral George B. McCleUan. Tbe history of the fifteen months that passed before Lincoln washed bis bands of this commander suffers from no lack of references toand to McCleUan's intelligence officer, tbe famous, or notorious, Allanuccessful Chicago detective. Tbe standard view of Mcaellan runs like this: Heuperb organizcr and administrator but was afflictedapoleonic complexast hesitancy to use the great army he built His super-caution and lhe failures that flowed from it were largely tbe result of Puikertoo's fantastic overestimates of Confederate strength.

This view stands op only as long as it takes toew of Pinker-ton's reports Pinkerton did habitually credit the opposing army (led by. Johnston and then by Lee) with two, three, and even four times its true strength. In this much the standard accounts are correct. What die historians have failed to noticeraudulence

McQellan could bave swallowed them.

Pinkertoo's basic order-oi-batde compilation was good enough.

This was someoo many, but the list Included every one ofhat the Confederates didnd his'asngnnjeot of these to brigades and divisions, though less complete and correct than his list of regiments, was good enough to refute the charge that he and bis bureau were totally incompetent.

But if he cniizzed his scurces to get an average strengthrigade or regiment, be did not extrapolate thisigure for the entire army. Instead he derived what hemedium estimate" or "general estimate" byound average of numerous gross estimates of the total enemy force. These grass figures be obtained from everyone wbo wouldhose sourcealmost never better than mere campt,rem and refugees (source; rumor or pureeserters (frequent source: careful instructionsonfederateod spies (who seldom if ever came by any halfway official figures).

The shabbiness of this method showed clearly In Pinkertoo'*so clearly thatasual reader should have rejected bis conclusions. There also was an external reason for rejectingcommon sense. Theyy the time Lee got to his top strengthhis total, and the earlier ones, could not bave looked reasonable to anyone who stopped to consider the total manpower available to the South, and especially the number of weapons that the Confederates could lay hands on Such numbers in the Richmond area would have left atouple of their other key points so lightly defended that the Federal armies should have been able to move in almost at will.

Finally, there is hista best illustrated byTus'

Early in Model lau's campaign that number was much smaller than the number the Confederates obviously had. This meant. Pinkerton argued, that the general estimates must also be much too small* Latter oo be purged bis reports of this non-sequitur only to replace it with another. When he had identified four times as many regiments, he again said the general estimate must be well below the truetime because organizational specifics indicated soumber of regiments.

This line of reasoning led him, by the timehart was fairly complete, into an even more absurd position. Saying that thereubstantial number of additional troops in units not part of the known enemy force was tantamount to saying there were additionaleven another entiretbe enemy lines, from which he had neveringle prisoner orand about whose eadstence he bad neverreath ofthe divisions he did have represented were well filled out with regiments and brigades.

If any belief in Pinkerton't estimates remained after the method of arriving at themertood. it must have been destroyed by this display. The question arises how McCleUan could have toleratedorry intelligence job. There is no answer until it isthat be was constantly Insisting oo his need for more men aad

How be could bave expected to exert leverage with such patent nonsense is another question. So far as this can have an answer, the answer must be that his estimate of the credulityountrified President was practically unbounded. One doubts that he even had the good taste to give Lincoln only gross figures and withhold the supporting "reasoning" Suspicion of the estimates was not confined to McClellan's superiors; even the Quartermaster Ceneral was aware of the fraud, and in fact it was be wbo rose to suggest that such rersortJng might be the work of disloyal hands.

While occupied in tbe Valley with General Banks, be waswith an attack on Staunton by other Federal forces back in tbe AUeghcnics. His first act in countering this tlireat was toseudo-desertcr into Banks' campeport that he was moving to Richmond. In order to make the story stick, he actually marched his men over the Blue Ridge and put themrain. It was typical of Jackson to assure that the waiting train would be beaded east Then to the surprise even of bis innrrediate subordinates, be ordered the train's crew to take ft to Staunton, whither it steamed in reverse, back over tbe Blue Ridge and across the Valley.

All this was supposed to set Banks in motion eastward. Butreckoned without the incompetence of Banks' information service. Banks failed to detect the march across the mountains, be

While our ait en tion Is directed to the Valley we may as well dispose of the Belle Boyd legend. Belle, barely eighteen at this time, owes ber fameeckless trip afoot to deliver mfcausation to Jackson as he arrived before Front Royal to achieve the mamhis celebrated Valley campaign. Banksmall outpost at Front Royal which Stonewall surprised and overran, thereby outhartldng his opponent and forcing him to retire across the Potomac Miss Boyd is raid to have made ber way, clad fn white, out of the town and across hills and fields, finding the Confederates by tbe sound of their guns.

Tbe story fa true enough, but ber reformation could bave bad belle or no value; It is unfair to Jackson to credit any part of his success to her supposedly fortuitous appearance. Jackson believed inend good planning. What happened at Front Royal was exactly what he had planned, aod tbe basis of his plan was some careful intelligence work. For two weeks be had been diligently collecting information from cavalry, citizens, prisoners, deserters, and spies. Evidently his conclusion from this wu that he could probably strike Front Royal with complete surprise.

Belle Boyd may have contributed to this information, but that is not what she is famous for. It would be hard to establish that she wasonfederate spy. but equally hard to say that the foolhardy act for which she is chiefly known was one of espionage-Miss Boyd literally flouted the fire of the Yankees. Mrs. Creenliow bad done the same thing only figuratively, but so braienly that she soonisit from the gentlemen of Pinkertoo's bureau. Both women seem to have been ruled by an impulsiveness that ill suited them to espionage. The main point of intemst in the Boyd case fa the fact that the Front Royal story has survivedair-raising example of Civil War mtelhgence operations. Such is the poverty of tbe literature.

John Pope or. Lee

It has been shown that McClellan was an even greater son-user of intelligence than history has made him. John Pope has also had the reputation of being an abominably informed commander; in his

uac unly

case the verdict must be considerably softened and his campaign reevaluated.

Pope became Lee's victim al Second Bull Run because be lostof tbe situation once tbe armies were at dose grips. This much bas been known, and it would be bard to overstate the extent of Pope's misunderstandings on tbe batUefiekL But it bas not been noticed that up to that point he had provided himself with excellent information arid had bandied his army very iklllfuDy Co tho basis of It-Pope In2 wax given command of the various forces that Jackson bad kept so well occupied in and near tbe Valley. Tbe new commander moved bis array east of the Blue Ridge, as rf to threaten Richmond, while McCIeuan was engaged with Lee on the opposite side of the enemy capital. Lee, after driving McCleUan away from the gates of tbe city, began detaching forces against Pope, who was maintaining an exposed positionone too numerous army.

Pope bad given his subordinates stern orders to use spies and maintain an active search for udonnation. Though be had the same small cavalry force from which Banks bad got so little results, be drove it to tbe limit Through this insistence and persistence he kept track of the Confederate buildup in his front as each new detachment arrived. Ills possession of firm information does much to explain his willingness to expose hisubject that has brought puzzled or critical comments from many historians.

In August, whenrmy was ordered back up theIts initial embarkations at Fort Monroe gave Lee tbe signal to turn on Pope in full force. By rail be suddenly moved out, taking the bulk of the army then still at Richmond. He concentrated, well coveredountain, directly across the Rapidan from Pope.

Moving from Richmond with tbe Confederates was one of Pope'sergeant in an Indiana cavalry regiment. In tbe role of pseudo-deserter be hadob as kxwnotive engineer with tbe Confederates. He jumped the train on which beassenger at the time, filtered through Lee's camps sotneltow, swam or waded the Rapidan, and was lucky enough to find Popeorward headquarters near the river. Pope pulled out of the trap as it was almost ready to spring.

The literature often gives intelligence credit for Pope's escape, ibis heartening historiogrsphtcal uDeraLty, however, singles out tbe wrong piece ofdispatchederal cavalry party captured, along with Jeb Stuart's adjutant and Job's 'own famous plumed hat.
