What events took place prior to the Long Walk?
a.
Army horses took over Canyon de Chelly grazing grounds.
b.
In 1860, 1,000 warriors attacked Fort Defiance.
c.
For 10 years there were attacks and reprisals by both the Navajo and the Army.
d.
All of the above.

1- The correct option is A. Native American slavery was a longstanding practice in New Mexico. Slaves in the Indian territory of the United States were used for many purposes, from work in the eastern plantations to guides in the desert, to work in the deserts of the west or as soldiers in wars. Native American slaves suffered from European diseases and inhumane treatment, and many died in captivity.

2- The correct option is D, as all the mentioned events took place prior to the Long Walk.

Option A refers to the Battle of Canyon de Chelly, which happened in January, 1864. In it, some of Carson's men marched through Canyon de Chelly, destroying Navajo properties. Without food or shelter to spend the winters, and continuously persecuted by the army, Navajo groups began to surrender.

Option B refers to the Second Battle of Fort Defiance, when 1000 Navajo warriors attacked the US Army garrison in then New Mexico territory, on August 30, 1960.

Option C refers to the clashes that happened between 1851 (when Colonel Edwin Vose Summer established Fort Defiance in Navajo territories) and 1861 (when a truce betweem the United States and the Navajo people was signed).

So, as we can see, all the listed events occurred prior to the Long Walk, which started in mid-1864.
