The expedition left
Brooklyn Navy Yard aboard the steamer
Diana on 2 July 1913. Two weeks later, at midnight on 16 July, the
Diana struck rocks while trying to avoid an
iceberg. MacMillan blamed the collision on the captain, who was drunk at the time. The expedition transferred to another ship, the
Erik, and eventually arrived at
Etah, in north-west
Greenland, on the second week of August. The next three weeks were spent constructing a large eight-room shed, with electricity generation capabilities, that was to serve as the local headquarters of the expedition. An attempt was also made to set up a radio room, but it was not successful, and the expedition was never able to establish reliable radio communications with the outside world. After making a number of preliminary trips to place supply caches along the route, MacMillan, Green, Ekblaw and seven
Inuit set off on the journey to Crocker Land on 11 March 1914. The temperature was many degrees below zero and weather conditions were very poor. Eventually, the party reached the
Beitstadt Glacier, which took them three days to climb. The temperature dropped dramatically and Ekblaw suffered severe
frostbite. He was evacuated back to Etah by some of the Inuit. One by one, the other members of the party gave up and turned back. By the time the expedition reached the edge of the
Arctic Ocean on 11 April, only MacMillan, Green and two Inuit, Piugaattoq and Ittukusuk, remained. The four dog sleds set off across the treacherous sea ice, avoiding thin patches and expanses of open water, and eventually, on 21 April, the party saw what appeared to be a huge island on the north-western horizon. As MacMillan later said, "Hills, valleys, snow-capped peaks extending through at least one hundred and twenty degrees of the horizon.” Piugaattoq, an Inuk hunter with 20 years of experience of the area, explained that it was just an
illusion. He called it
poo-jok, which means '
mist'. However, MacMillan insisted they press on, even though it was late in the season and the sea ice was breaking up. For five days they went on, following the mirage. Finally, on 27 April, after they had covered some of dangerous sea ice, MacMillan was forced to admit that Piugaattoq was right—the land that they had sighted was in fact a mirage. (It was probably a rare form of mirage called a
Fata Morgana.) Later MacMillan wrote: The party turned around and was able to reach solid land—with no time to spare, for the sea ice broke up the next day. ==The killing of Piugaattoq==
