"Kerry got his first Purple Heart after alleged hostile fire, but nine days later he wrote in his journal, "We hadn't been shot at yet." No witnesses have come forward to tell us how Kerry's first Purple Heart came to be issued.
Then there was the mysterious third version of the Silver Star citation, an improved and glowing one that appeared late and that John Lehman, secretary of the Navy, said he didn't write or order to be written. Nobody came forward to explain how or why the citation improved over the years. Kerry refused to make public his journal or his full military records, and the media seemed uninterested in pushing for him to do so."
Gotten from here.
