Given the below context:  Prior to the Willie Company departing Florence, the company met to debate the wisdom of such a late departure. Because the emigrants were unfamiliar with the trail and the climate, they deferred to the returning missionaries and church agents. One of the returning missionaries, Levi Savage, urged them to spend the winter in Nebraska. He argued that such a late departure with a company consisting of the elderly, women, and young children would lead to suffering, sickness, and even death. All of the other church elders argued that the trip should go forward, expressing optimism that the company would be protected by divine intervention. Some members of the company, perhaps as many as 100, decided to spend the winter in Florence or in Iowa, but the majority, about 404 in number (including Savage) continued the journey west. The Willie Company left Florence on August 17 and the Martin Company on August 27. Two ox-wagon trains, led by captains W.B. Hodgett and John A. Hunt, followed the Martin Company.Near Wood River, Nebraska, a herd of bison caused the Willie Company's cattle to stampede, and nearly 30 cattle were lost. Left without enough cattle to pull all of the wagons, each handcart was required to take on an additional 100 pounds (45 kg) of flour.In early September, Franklin D. Richards, returning from Europe where he had served as the church's mission president, passed the emigrant companies. Richards and the 12 returning missionaries who accompanied him, traveling in carriages and light wagons pulled by horses and mules, pressed on to Utah to obtain assistance for the emigrants.  Guess a valid title for it!
