Operation Washing was the successful destruction of the railway bridge over the Asopos River in Central Greece by four British SOE saboteurs. It took place on 21 June 1943, as part of Operation Animals. The British agents included Geoffrey Gordon-Creed and New Zealander Donald Stott. This was detailed in the book Rogue Male by Roger Field. In 1943, British forces planned a daring mission to destroy the heavily guarded Asopos viaduct in Greece, aiming to disrupt German railway communications. The mission, led by Captain Gordon-Creed and a small team, would prove to be a remarkable feat of sabotage.
