The point on which popular opinion was perhaps most widely and persistently wrong was, that the defeat of the first day arose from the fact that Grant's army was completely surprised. Public opinion, throughout the war, was formed in advance of the official reports of generals in three ways. There were many press correspondents with every army, and the main purpose of most of them was to construct an interesting story and get it into print as soon as possible. The National Government adopted the wise policy of giving the armies in the field such mail facilities as would keep the soldiers in close touch with their homes, and they wrote millions of letters every year. All that a soldier needed was some scrap of paper and some sort of pen or pencil. If he happened to have no postage stamp, he had only to mark his missive "Soldier's letter," and it would be carried in the mails to its destination, and the postage collected on delivery. After a battle every surviving soldier was especially anxious to let his family know that he had escaped any casualty, and he naturally filled up his letter with such particulars as had most impressed him in that small part of the field that he had seen, and sometimes with such exaggerated accounts as in the first excitement had reached {105} him from other parts. Finally, the journalists were not few who assumed to be accomplished strategists, and talked learnedly in their editorial columns of the errors of generals and the way that battles should have been fought. And some of them had political reasons for writing up certain generals and writing down certain others. [Illustration: MAP SHOWING ROADS AND POSITION OF CAMPS BEFORE AND DURING THE BATTLE OF SHILOH.]
