The surface-raider section opens with Admiral Graf Spee changing her appearance during the cruise. The visible changes could encourage an observer to report an American cruiser or a different warship. The disguise did not make the hull literally disappear; it made contact reports less reliable and slowed the process of linking sightings across a vast ocean. Physical alteration therefore served the same strategic aim as radio silence and route uncertainty by weakening the defender's picture of where the raider had been.
