"Dresden", after escaping at the Battle of the Falkland Islands on 8 December, was sheltering in the waters south of the Straits of Magellan with British forces under Rear Admiral Archibald Stoddart actively searching for her location. "Sierra Cordoba" was then known to be a raider supply ship and had cleared Montevideo, supposedly for Callao, Peru on 18 December with supplies of coal and water. On 26 December in "Snug Bay" Admiral Stoddart found "Sierra Cordoba" but could take no action beyond briefly boarding due to the fact a Chilean destroyer was observing his movements and it was presumed Chileans were observing the merchant vessel for neutrality violations. "Sierra Cordoba" joined "Dresden" and continued to supply the cruiser until 14 February 1915 when "Dresden" put to sea. Both ships moved northward off the coast of Chile, with the cruiser coaling several times, until "Sierra Cordoba" was dismissed after spending three days coaling the raider before heading into Valparaiso for coal. "Sierra Cordoba" departed Valparaiso on 7 March, coaled "Dresden" at Juan Fernández Islands 9 March, and eventually put into Callao as the cruiser had been sunk five days after the meeting.
