Its goal was the exploration of the North American coast between the mouths of the Mackenzie and Coppermine rivers and Bering Strait, in what is now present-day Alaska, Yukon, the Northwest Territories, and Nunavut.
Beginning in the early 19th century, the Royal Navy, having expanded to unprecedented proportions during the Napoleonic Wars, turned much of its attention to the passage's discovery.
In 1819, he was chosen to lead an expedition whose intention was to map the northern coast of the North American continent eastwards from the mouth of the Coppermine River.
The Coppermine expedition was by any objective standard a disaster; Franklin completely failed in his goal of mapping a sufficient portion of the Arctic coast, and half of his 22-strong party died over the course of the journey.
In accordance with his official instructions, he was to first spend the summer of 1825 travelling to Great Bear Lake via standard trading routes, where the party's winter quarters would have been constructed.
Applying this knowledge to his new expedition, Franklin sought to place greater trust in British naval personnel and, most critically, to bring sufficient supplies for the duration of the journey.
Although canoes of birch bark were the de facto standard for travel along North America's internal waterways, Franklin judged them unfit for navigation in the open waters of the Arctic Ocean.
Simultaneously, most of the expedition's supplies were sent from York Factory on Hudson Bay up the Hayes River, reaching the officers at Methye Portage on 29 June.
The party's expeditious pace can be attributed to their intense rowing efforts: during their last push to Great Slave Lake, they had been paddling for thirty-six of the thirty-nine preceding hours.
After coasting the southern shore of Great Slave Lake, the party reached the headwaters of the Mackenzie River on 3 August, which would thereafter be their route to the Arctic Ocean.
[9] At Fort Norman, realizing that their speedy pace afforded them additional time for exploration, Franklin opted to embark on a preliminary reconnaissance to the mouth of the Mackenzie River, while the rest of the party would continue to Great Bear Lake to oversee the construction of their winter quarters.
After completing their early charting, the group returned to the Mackenzie River proper, reaching Fort Franklin (modern day Délı̨nę) on Great Bear Lake on 5 September.
On 8 September, Franklin dispatched two men to Great Slave Lake to convey an account of the expedition's progress and to pick up letters sent from the Crown.
[citation needed] As recorded in Franklin's journal, during the winter of 1825–1826, to pass the time, the men played a game very similar to modern ice hockey.
Franklin at this point grew displeased with the constant presence of the Dog-Rib Indians, claiming that they "continued hanging about the fort, and their daily drumming and singing over the sick, the squalling of the children, and bawling of the men and women, proved no small annoyance.
Supplies and men were then divided between the western and eastern detachment, and after final preparations were made, the party departed from Fort Franklin on the summer solstice of 1826.
He would then ascend the river and cross overland to Great Bear Lake, ideally arriving at Fort Franklin before the onset of winter.
After instructing Back and the others to be prepared to take up arms should the Inuit prove hostile, Franklin departed for the camp, alongside the party's interpreter, Tattannoeuck (Augustus).
Western travel along the Arctic coast was arduous: temperatures seldom exceeded 6 °C (43 °F), and gusts of wind frequently upended the expeditionaries' tents, making sheltering from the rain difficult.
On 16 August, realizing that summer was coming to an end and the navigability of the rest of the party's route would be threatened by increasingly poor conditions, Franklin decided they would turn back towards the Mackenzie's mouth.
Under the pretence of helping the Europeans navigate the river, the Mountain Indians would then stave in their boats, making them unfit for escape to deeper waters; then a larger group would rush out of a predesignated hiding spot and attack.
Each man was allotted 9 kg (20 lb) of pemmican, in addition to packages of macaroni, dry soup mix, chocolate, sugar, and tea.
In addition, the group carried a portable boat; blankets; spare guns, shoes, and ammunition; fishing nets; kettles; and hatchets.
Many among the party were unaccustomed to carrying such heavy loads, but upon examining the group's stocks, Richardson found little that he considered superfluous enough to discard.
[23] Richardson attributed much of their exertion to the frequent change of elevation and the spongy, wet ground and resulting absence of secure footing.
After sending out hunting excursions to enlarge the expedition larder in preparation for their push to Fort Franklin, on 21 August, Richardson and the scouting party were united.
Kendall returned to the fort on 8 October, carrying an abundance of food and other supplies, which were of particular benefit to the eastern detachment, who had been forced to sacrifice much of their equipment during their overland crossing between the Coppermine and Dease Rivers.
During the breaking of the party at Point Separation, he realized the contrast between his situation and the previous expedition, writing that "it was impossible not to be struck with the difference between our present complete state of equipment and that on which we had embarked on our former disastrous voyage.
Instead of a frail bark canoe, and a scanty supply of food, we were now about to commence the sea voyage in excellent boats, stored with three months' provision.
In Mackenzie's mind, having reached the wrong ocean, he turned back in disappointment and returned to Britain, where his efforts were not widely recognized.
