On the 21st March, Cagni decided to take three men with him in the third or advance detachment. He found it necessary to send two men forward to prepare the way for the sledges. With three men in the detachment, only one would be left to look after the most of the dogs and sledges. He therefore decided to send back three men in the first detachment, instead of four. To meet the extra rations required for the additional man, he intended to send back the first detachment two days, and the second detachment four days earlier than originally intended. The first detachment, composed of Lieutenant Querini, the guide Ollier, and the engineer Stökken, was sent back on the 23rd March. At this time the expedition was about 45 miles distant from the island which had been seen two days previously. Nothing more was ever heard of this detachment. The Duke came to the conclusion that an accident must have happened. It is quite possible, however, if not probable, that the party was drifted so far out of the proper course that the island could not be reached before all the food had been consumed. It will be seen that the third detachment failed to make headway against this drift, and was saved only by giving up the attempt to reach Prince Rudolf Island, and by making its way towards the islands in the south. Some of the dogs caused a great deal of trouble. One had deserted on two occasions. It was a fine, strong animal, and it would have been a pity to kill it. The doctor undertook to tame it and prevent it deserting. He secured it with two chains and a steel-wire rope. In spite of this, it was found trying to escape, and the doctor gave it a severe beating. During the night the dog broke the two chains, and in some incredible way managed to get free. As if to be revenged on its tamer, it made a hole in the doctor’s tent and stole all the butter which was to serve for the detachment’s breakfast. Towards the end of March the temperature was still very low, and Captain Cagni suffered greatly from one of his forefingers which had already been twice frost-bitten. The sleeping-bag slowly filled with snow formed by the frozen moisture of the breath. During the night their bodies gradually thawed this snow, and they rose in a cold bath in the morning. Soon after getting up, the moisture froze again into a mass of ice. On 27th and 28th March the temperature was more than 40° F. below zero. On the 28th March, Captain Cagni was able to take an observation for latitude, and was astonished to find that it was only 83°. He had calculated that it ought to be about 83° 50′. The drift to the south must therefore have been considerable.
