Based on what most sources say, I would agree. Sometimes the name 'Pittsburg Landing' appears in Confederate accounts, but not often. It's seen more often in Federal accounts, but even there the predominant name is Shiloh. For instance, in Dyer's Compendium, Pittsburg Landing is the name used in the battles and skirmishes index for Tennessee. However, Federal regimental records published in Dyer's all use the name Shiloh.

Except for those captured during this brief campaign and battle, few Confederates got a good look at Pittsburg Landing. In contrast Federal accounts uniformly name Pittsburg Landing as a station or camp. For that reason alone I would associate the name with the Federal army.

In Gerald's defense, since no community of any size existed nearby, some early accounts of the fighting used the name 'Pittsburg Landing' or simply 'Pittsburg'.

Here are a couple of examples from the Mobile Advertiser and Register which use both names. I must say that far fewer examples of the Pittsburg name appeared than I expected --

The battle field of Shiloh will be memorable in the annals of Mobile, because it has been stained by the blood and illustrated by the gallantry of her sons. That name, like the music of Carroll, will be sweet yet mournful to her soul, and when the appointed pen shall come to weave the strands of the stirring incidents into the enduring cord of history, the laurel and the cypress will be found closely blended. Alas! That Military Fame must be dappled in the blood of the brave! Alas! That the shouts of victory and the noble exaltation which stirs generous minds to praise and admiration of heroic action, should be mingled with the wail of bereaved hearts over their loved ones lost!

Sunday closed on a brilliant victory for our arms. A new army reached Pittsburg during the night, and the contest was renewed and raged with fury on our whole line during the forenoon of Monday. Alternate success crowned the efforts of each army, but the reinforcements and thousands of fresh troops of our enemy were telling on our brave but wearied soldiers. At noon the firing had ceased on the right wing of our army. It still raged in the centre, where our brave troops, under Gen. Beauregard on the right and Gen. Bragg on the left, seemed to perform the work of superhuman agents. Again and again did they dash against the foe and drive them back, to be in turn forced back by the endless succession of fresh foes and new batteries. At last the firing grew lighter on the right of the centre, slackened to the volleys of companies, then of platoons, then to occasional shots, and then ceased altogether.

Mrs. Jacob Walker, Mobile, Ala.:

Your son, Eugene B. Walker, is here in the hospital; was shot through the right shoulder on Sunday, the first day of the battle at Pittsburg. The next day (Monday) the Union army took him prisoner of war, and sent him here under the care of the Surgeon. He is doing very well, and well cared for, and hopes to be about soon.
G. M. Parke was here a prisoner of war, “unhurt”, captured on Monday at the same place. I think he has been sent to Columbus, Ohio.

Yours, truly, J. F. CUNNINGHAM
