I found this while looking into Abraham Lincoln because he was in a post of mine in GDP.

WASHINGTON - It was a historian's dream: alone in dimly lighted stacks, leafing through hundreds of yellowed papers and stumbling across a document that clarifies a pivotal moment in U.S. history.
"It was kind of a shock," said Trevor Plante, an archivist at the National Archives, about finding a letter written by Abraham Lincoln after the Union victory at Gettysburg.
The note was dated July 7, 1863, just a few days after two Union victories that followed a string of humbling defeats. Lincoln wrote the note to Maj. Gen. Henry W. Halleck, the Union general in chief, pushing him to urge Maj. Gen. George G. Meade to capitalize on the Gettysburg victory and pursue retreating Confederate forces led by Gen. Robert E. Lee.
"We have certain information that Vicksburg surrendered to General Grant on the 4th of July," the letter says. "Now, if Gen. Meade can complete his work so gloriously prosecuted thus far, by the litteral or substantial destruction of Lee's army, the rebellion will be over."
Halleck forwarded the two sentences via telegram on July 7 from Washington to Meade at Gettysburg.
The one-paragraph note has been quoted for years but until now it was not clear that the quotations were verbatim. The whereabouts of the original document was also a mystery.
