Brigham Young, the President of the Quorum of the Twelve Apostles, sent Elder Jesse C. Little to Washington, D.C., to seek assistance from the federal government for the Mormon Pioneers fleeing from the Illinois mobs. Little arrived in Washington D.C. on May 21, 1846, only eight days after Congress had declared war on Mexico. Pennsylvania Army officer and attorney Thomas L. Kane offered the Mormons his advice and assistance. Politically well connected through his jurist father, Kane provided letters of recommendation and joined Little in Washington, D.C. The two called on the Secretary of State, Secretary of War, and President James K. Polk. After several interviews in early June 1846, President Polk agreed to Little's offer if "a few hundred" men enlisted. On June 2, 1846, President Polk wrote in his diary: "Col. W. Kearny was ... authorized to receive into service as volunteers a few hundred of the Mormons who are now on their way to California, with a view to conciliate them, attach them to our country, and prevent them from taking part against us."
