Confabulation (verb: confabulate) is a memory disturbance, defined as the production of fabricated, distorted or misinterpreted memories about oneself or the world, without the conscious intention to deceive.[1] Confabulation is distinguished from lying as there is no intent to deceive and the person is unaware the information is false.[2] Although individuals can present blatantly false information, confabulation can also seem to be coherent, internally consistent, and relatively normal.[2] Individuals who confabulate present incorrect memories ranging from "subtle alterations to bizarre fabrications",[3] and are generally very confident about their recollections, despite contradictory evidence.[4] Most known cases of confabulation are symptomatic of brain damage or dementias, such as aneurysm, Alzheimer's disease, or Wernicke–Korsakoff syndrome (a common manifestation of thiamine deficiency caused by alcoholism.)

Maybe he was a confabulator. They didn't exactly have B complex vitamins for the prisoners on the Dry Tortugas and I believe he was a heavy drinker before the trial. He was a confabulator in regards to Weichmann, too, since Atzerodt never incriminated him in any of his many confessions.
