Blaxland was born in Kent, in 1771, and arrived in the colony in 1806, accompanied by his wife and three children. He settled down to the congenial occupation of stockbreeding, on what was then considered to be a large scale. Finding that his stock did not thrive so well in the immediate neighbourhood of the sea coast, and wanting more land for pasturing his increasing herds, he made anxious enquiries in all directions as to the possibility of crossing the Blue Mountains inland. Nobody would entertain such a suggestion, the failures had been too many: every one to whom he broached the subject declared it to be impossible, prophesying that the extension of the settlement westward would forever be obstructed by their unscalable heights. Blaxland, however, was not intimidated by these disheartening predictions; and, in 1811, he started out on a short journey of investigation, in company with three Europeans and two natives. On this trip he found that by keeping on the crowning ridge or dividing water-shed between the streams running into the Nepean and those that fed what he then took to be an inland river, he got along fairly well. Some time afterwards he accompanied the Governor in a boat excursion up the Warragamba, a tributary of the Nepean, and though there were no noteworthy results, it convinced Blaxland that, could he follow his former tactics of adhering to the leading ridge that formed the divide between the tributaries of the northern bank of this river and the affluents of the Grose, a tributary of the Hawkesbury, he would attain his object and reach the highlands. It will thus be seen that Blaxland acted with a definite and well-thought-out mode of procedure; and that the ridge he selected for the attempt was chosen with judgment based on considerable knowledge of the locality, which he gained from many talks with the men who hunted and frequented the foothills of the range. Finally, when he had arranged his plan of assault, he confided his intention to two friends, Lieutenant William Lawson and William Charles Wentworth, whose names are associated with his in the conquest of the Mountains. They both consented to accompany him, and agreed to follow his idea of stubbornly following one leading spur. Blaxland's former expedition had convinced him that the local knowledge of the natives did not extend far enough to be of any service, and they therefore did not take any aborigines with them. They took pack-horses, however, which proves that the party started with a well-founded faith in their ultimate success, and gave no heed to the terrifying descriptions of former travellers.
The besetting hindrance to their progress was the low scrub of brushwood that greatly delayed the pack-horses. This obstacle was overcome only by patiently advancing before the horses every afternoon, and cutting a bridle-track for the succeeding day's stage. Thus literally, the way that ultimately led into the interior was won by foot, and the little pioneering band eventually descended into open grazing country at the head of what is now known as the Cox River. The outward and return trip occupied less than one month's time; which speaks volumes for the wise choice of route; but what says more, is the fact that no better natural, upward pathway has since been found.
Routes of Blaxland, Wentworth, and Lawson (1813); Evans (1813); Oxley (1817, 1818, 1823); and Sturt (1828 and 1829).
A synopsis of Blaxland's journal is given here, commencing with a few quoted lines of preamble:--
"On Tuesday, May 11th, 1813, Mr. Gregory Blaxland, Mr. William Wentworth and Lieutenant Lawson, attended by four servants, with five dogs and four horses laden with provisions and other necessaries, left Mr. Blaxland's farm at South Creek for the purpose of endeavouring to affect a passage over the Blue Mountains, between the Western River* and the River Grose...The distance travelled on this and subsequent days was computed by time, the rate being estimated at about two miles per hour."
*[Footnote.] The Warragamba.
They camped at the foot of the ridge that was to witness the last struggle between man and the Mountains. On the first day, they did three miles and a half in a direction varying from south-west to west-north-west, and that night obtained a little grass for the horses, and some water in a rocky hole.
The heavy dews in the morning retarded any attempts at early departures, as the thick wet brush rendered it difficult to drive the horses, so that, as a rule, it was nine o'clock before they were able to strike camp. The ridge, still favouring the direction of west and north-west, on the third day they arrived at a tract of land, hilly, but with tolerable grass on it. Here they found traces of a former white visitant in the shape of a marked-tree line. Two miles from this point, they met with a belt of brushwood so dense that for the first time they were forced to alter their course; but the subordinate spurs on either side ending in rocky precipices, they had to return and again confront the scrub. In these circumstances, they made up their minds to rely upon axe and tomahawk to win a way, and so next morning fell to work cutting a passage for the horses. The ascent was also now becoming steep and rough, and on this day some of the horses fell while struggling up with their loads.
