Philadelphia ? An intern with the National Archives stole about 165 Civil War documents – including the War Department’s announcement of President Lincoln’s death – and sold most of them on eBay, prosecutors charged Thursday.

Denning McTague, who runs a Web site that sells rare books, worked last summer at a National Archives and Records Administration site in Philadelphia, prosecutors said.

McTague, 40, of Philadelphia, has helped officials recover most of the missing items and plans to plead guilty, his lawyer said.

The stolen documents include telegrams concerning troops’ weaponry, the Lincoln death announcement sent to soldiers and a letter from famed Confederate cavalryman James Ewell Brown “Jeb” Stuart, prosecutors said.

The sale of one of the items on eBay aroused suspicion and led to the investigation, National Archives spokeswoman Susan Cooper said.
