They founded the village to help those who did not have enough means to continue their journey, as well as to hold and supply innovative companies of pioneers.

When Brigham Young and the main company left Garden Grove upon May 12, 1846, the poorest and least prepared were left behind.

Brigham Young and further leaders rode assist as in the distance as Mt. Pisgah to incite the men to enlist, and a letter was sent to the Saints in Garden Grove. Only one man from the Garden Grove settlement, Edward Bunker, enlisted and served in the Mormon Battalion.

Two rescue parties were sent from Winter Quarters and Council Bluffs, and an additional group was requested from Garden Grove. Luman Shurtliff led the third rescue party and brought the poorest of the exiles to the pact at Garden Grove.
