Prince Frederick settled Anderson in a former army barracks in the small village of Unterlengenhardt, on the edge of the Black Forest, where she became a sort of tourist attraction. Lili Dehn, a friend of Tsarina Alexandra, visited her and acknowledged her as Anastasia, but when Charles Sydney Gibbes, English tutor to the imperial children, met Anderson he denounced her as a fraud. In an affidavit, he swore "She in no way resembles the true Grand Duchess Anastasia that I had known ... I am quite satisfied that she is an impostor." She became a recluse, surrounded by cats, and her house began to decay. In May 1968, Anderson was taken to a hospital at Neuenbürg after being discovered semi-conscious in her cottage. In her absence, Prince Frederick cleaned up the property by order of the local board of health. Her Irish Wolfhound and 60 cats were put to death. Horrified by this, Anderson accepted her long-term supporter Gleb Botkin's offer to move back to the United States.
