Passage: Col. Edwin Sumner conducted a campaign against the Navajo in 1851. He delegated Maj. Electus Backus to build Fort Defiance in the middle of Dine bikeyah . Col Sumner entered Canyon de Chelly but Navajo harassment attacks caused him to withdraw. In 1855 a treaty was signed at Laguna Negra by Manuelito and Zarcillos Largos for the Navajo and Henry L. Dodge , Governor Merriweather, and General John Garland. Two years later a severe drought hit the Navajo and decimated their livestock and agricultural resources, causing a famine in the winter of 1857-1858. A time of social disruption ensued. Surrounding tribes gradually increased their attacks on the weakened Navajo. The Navajo demanded in 1858 that Fort Defiance stop grazing their livestock on prime Navajo land. Soldiers shot 48 cattle and 8 horses belonging to Manuelito. Navajo warriors killed a servant of the commanding officer in retaliation for the killing of their people's livestock without compensation. The United States military demanded the murderer be brought to them, or they would begin a war. The Miles Campaign was sent against them, leaving Fort Defiance on September 9.
Question: What year did a severe drought hit the Navajo?

Passage: Hoping to rebound from their divisional home loss to the Patriots, the Jets flew to Qualcomm Stadium for a Week 3 MNF duel with the San Diego Chargers. In the first quarter, New York took flight as CB David Barrett returned an interception 25 yards for a touchdown. The Chargers responded with kicker Nate Kaeding getting a 36-yard field goal, along with QB Philip Rivers completing a 1-yard TD pass to FB Mike Tolbert. In the second quarter, San Diego increased its lead with CB Antonio Cromartie returning an interception 52 yards for a touchdown.

In the fourth quarter, New York tried to rally as Favre completed a 4-yard TD pass to WR Chansi Stuckey (with a failed 2-point conversion), along with kicker Jay Feely getting a 32-yard field goal, yet the Chargers answered with Tomlinson's 2-yard TD run. Afterwards, the Jets tried to make yet another comeback attempt as Jerricho Cotchery ran a return ball 54 yards.
