Former Taliban hostage weighs in on Bergdahl letters

(CNN) – In letters reportedly written by U.S. Army Sgt. Bowe Bergdahl to his family while in captivity, he seems to acknowledge the curious circumstances surrounding his disappearance. The Daily Beast published two letters from Bergdahl, one from 2012 and one from 2013, that were obtained by sources in contact with the Taliban.

In the letters – dated 2012 and 2013 – Bergdahl discusses his life and partially explains why he disappeared in 2009.

"To my friends & family, in regards to the circomestance (sic) here, I am as well as can be here," he wrote. "I am given food and drink."

The letters have several grammatical errors, and the handwriting is different from one letter to the other. But if true, these letters provide more insight into Bergdahl's thinking while being held captive.

"Bergdahl is writing this letter under duress," says Reuters reporter David Rohde, who was kidnapped in Afghanistan by the Taliban while doing research for a book and held for seven months before he escaped.

While in captivity, Rohde wrote a letter to his family that got out.

"The Taliban are watching you write it, they're making copies of the letter, you're not going to be able to speak freely in the letter," said Rohde.

Bergdahl had harsh words for Army leadership.

"Leadership was lacking, if not non-existent. The conditions were bad and looked to be getting worse for the men that where actuly (sic) the ones risking thier (sic) lives from attack," he wrote.

"If this letter makes it to the U.S.A., tell those involved in the investigation that there are more sides to the cittuwation (sic)," Bergdahl said. "Please tell D.C. to wait for all evadince (sic) to come in."

"This is a clue about why he left the base, but it's not definitive," said Rohde.
