An item referred apparently to an account of sailor who passed with his ship several harbours on the Romanian part of the Lower Danube. He stated that while in the harbour of Braila he sighted two speedboats. One was gray painted, with a short pole mast and searchlight on the bridge and forward was a small machine gun mounted. She was flying the Romanian war flag.
