Entertaining the views I have explained in my last chapter, I wrote in January, 1843, to Lord Stanley, at that time Her Majesty’s principal Secretary of State for the Colonies, tendering my services to lead an expedition from South Australia into the interior of the Australian continent.  As I was personally unknown to Lord Stanley, I wrote at the same time to Sir Ralph Darling, under whose auspices I had first commenced my career as an explorer, to ask his advice on so important an occasion.  Immediately on the receipt of my letter, Sir Ralph addressed a communication to the Secretary of State, in terms that induced his Lordship to avail himself of my offer.

In May, 1844, Captain Grey, the Governor of South Australia, received a private letter from Lord Stanley, referring to a despatch his Lordship had already written to him, to authorise the fitting out of an expedition to proceed under my command into the interior.  This despatch, however, did not come to hand until the end of June, but on the receipt of it Captain Grey empowered me to organise an expedition, on the modified plan on which Lord Stanley had determined.

Aware as I was of the importance of the season in such a climate as that of Australia, I had written both to the Secretary of State, and to Sir Ralph Darling, so that I might have time after the receipt of replies from Europe, in the event of my proposals being favourably entertained, to make my preparations, and commence my journey at the most propitious season of the year, but my letter to Sir Ralph Darling unfortunately miscarried, and did not reach him until three months after its arrival in England.  The further delay which took place in the receipt of Lord Stanley’s despatch, necessarily threw it late in the season before I commenced my preparations for the long and trying task that was before me.  By the end of July, however, my arrangements were completed, and my party organised, and only awaited the decision of Mr. John Browne, the younger of two brothers who were independent settlers in the province, whose services I was anxious to secure as the medical officer to the expedition, to fix on the day when it should leave Adelaide.

On the 4th of the month (August), I saw Mr. W. Browne, who informed me that his brother had determined to accept my proposals, and that he would join me with the least possible delay; upon which I felt myself at liberty to make definitive arrangements, and to direct that the main body of the expedition should commence its journey on Saturday, the 10th.  On the morning of that day I attended a public breakfast, to which I had been invited by the colonists, at the conclusion of which the party, under the charge of Mr. L. Piesse (who subsequently acted as storekeeper) proceeded to the Dry Creek, a small station about five miles from Adelaide.  At that place he halted for the night.  Mr. Browne not having yet joined me, I kept Davenport, one of the men, who was to attend on the officers, with a riding horse for his use, and the spring cart (in which the instruments were to be carried), for the purpose of forwarding his baggage to the Murray, on the banks of which the party was to muster.
