After leaving Eucla, the explorers had a distressing stage to the head of the Great Bight, where they finally obtained water by digging in the sand. On this stage the horses suffered more than on any previous one, having had to travel three days without a drink. From this point they soon reached the settled districts of South Australia in safety.
Although this journey of Forrest's cannot strictly be called an exploring expedition, inasmuch as he repeated the journey made under such terrible conditions by Eyre travelling in the opposite direction, yet it is of first-rate importance, inasmuch as, owing to the greater facilities he enjoyed, he was able to pronounce a more final verdict than Eyre was able to give. Forrest found that the gloomy thicket was a fringe confined to the immediate coast-line. On every occasion that he penetrated it, he came on good pastoral land beyond. He writes:--
"The country passed over between longitude 126 degrees 24 minutes and 128 degrees 30 minutes East as a grazing country far surpasses anything I have ever seen. There is nothing in the settled portion of Western Australia equal to it, either in extent or quality; but the absence of permanent water is a great drawback...The country is very level, with scarcely any undulation, and becomes clearer as you proceed north."
On his arrival in Adelaide he received a hearty welcome, and a similar reception was accorded him on his return to Perth. Unfortunately this expedition destroyed all hope of the existence of any river, the mouth of which might have been crossed unwittingly by Eyre.
We now come to that exploit which gained for Forrest a place in the foremost rank of Australian explorers. The western central desert had long defied the explorers in their attempts to cross its dread confines. But the young West Australian took his men and most of his horses through the very heart of the terrible desert. We have seen how three expeditions had started from the east for the purpose of making this continental traverse, all differently composed -- one with the aid of camels only, one with a composite equipment of both horses and camels, and the third with only horses. The successful expedition to be now recorded travelled from west to east, and crossed the desert with horses only.

On the 14th of April, 1874, Forrest left Yuin, then the border of settlement on the Murchison, accompanied by his brother Alexander, two white men, and two natives, to endeavour to cross the unknown stretch of desert country that separated the colonies of eastern Australia from the western settlements. Their route at first lay along the Murchison River, following the upper course, which they found to run through well-grassed country, available for either sheep or cattle. From the crest of the head watershed they had a view of their future travelling-ground to the eastward. It appeared level, with low elevations, but there was a lack of conspicuous hills, which did not promise favourably for water-finding, though good pasture might be obtainable.
For the next few days the party were dependent for water on occasional springs and scanty clay-pans. On the 27th, when following down a creek, they suddenly came upon a fine spring, apparently permanent, which is described by Forrest in his journal as one of the best he had ever seen, both the grass and other herbage around being of fine quality. This place he named Windich Springs, after Tommy Windich, one of the blacks who had now been with Forrest on three expeditions. To the north-west was a fine range of hills, which he named the Carnarvon Range. On leaving this oasis, the explorers found themselves in less attractive country; spinifex and sand became more frequent features of the landscape, and the occasional water-supply became precarious.
