workplace computer Manning had used between November 2009 and May 2010; 400,000 military reports from Iraq and 91,000 from Afghanistan on an SD card found in her basement room in her aunt's home in Potomac, Maryland; and 10,000 cables on her personal MacBook Pro and storage devices that they said had not been passed to WikiLeaks because a file was corrupted. They also recovered 14 to 15 pages of encrypted chats, in unallocated space on Manning's MacBook hard drive, between Manning and someone believed to be Julian Assange. Two of the chat handles, which used the Berlin Chaos Computer Club's domain (ccc.de), were associated with the names Julian Assange and Nathaniel Frank. Johnson said he found SSH logs on the MacBook that showed an SFTP connection, from an IP address that resolved to Manning's aunt's home, to a Swedish IP address with links to WikiLeaks. Also found was a text file named "Readme", attached to the logs and apparently written by Manning to Assange, which called the Iraq and Afghan War logs "possibly one of the most significant documents of our time, removing the fog of war and revealing the true nature of 21st century asymmetric warfare". The investigators testified they had also recovered an exchange from May 2010 between Manning and Eric Schmiedl, a Boston mathematician, in which Manning said she was the source of the Baghdad helicopter attack ("Collateral Murder") video. Johnson said there had been two attempts to delete the material from the MacBook. The operating system had been re-installed in January 2010, and on or around January 31, 2010, an attempt had been made to erase the hard drive by doing a "zero-fill", which involves overwriting material with zeroes. The material was recovered after the overwrite attempts from unallocated space. Manning's lawyers argued that the government had overstated the harm the release of the documents had caused and had overcharged Manning to force her to give evidence against Assange. The defense also raised questions about whether Manning's confusion over her gender identity affected her behavior and decision making. Guilty plea, trial, sentence The judge, Army Colonel Denise Lind, ruled in January 2013 that any sentence would be reduced by 112 days because of the treatment Manning received at Quantico. On February 28, Manning pleaded guilty to 10 of the 22 charges. Reading for over an hour from a 35-page statement, she said she had leaked the
