BRUNSWICK (AP) — Civil War general Joshua Chamberlain’s original Congressional Medal of Honor has arrived back in Brunswick.

The medal Chamberlain received in 1893 for his heroism at Little Round Top during the Battle of Gettysburg is at the Pejepscot Historical Society.

The historical society received the medal in an anonymous package in July but questioned its authenticity.

But historians verified that the medal was real. The Brunswick home where the Maine native lived more than 50 years is now a museum.

The Times Record reported (http://bit.ly/13Cuzyo ) that the medal was given to his granddaughter, whose estate was donated to the First Parish Church of Duxbury, Mass., following her death in 2000.

Someone found the medal in the pages of a book bought from the church and returned it to Brunswick.
