Stanley: Allardyce concluded that Dresden was mostly likely holed up at San José on the Argentine coast and, if an attack on the Falklands was contemplated, then it was imminent. He wrote: '... I reckoned that the Santa Isabel would take from two and a half to three days to reach San José, about half a day to transfer her provisions to the Dresden, and that the Dresden ...would take something under two and a half days to reach the Falkland Islands, so that we might expect her arrival on the 14th or 15th of this month.'
Dresden was at that time hiding amongst the islands around Cape Horn and coaling from the Baden which was accompanying her.
