Why did Lincoln fire so many of his top generals throughout the war?

Lincoln’s frustration and depression deepened as Union military defeats continued into 1863. The Union army had every advantage in resources, but failed to assemble the military leadership needed to mount a successful campaign.

Lincoln replaced generals and changed the command structure of the army several times before he finally selected Ulysses S. Grant to take command. He had gained Lincoln’s confidence after winning crucial victories at Vicksburg, Mississippi, and elsewhere in the West. In Grant, Lincoln had finally found a general who would muster the full strength of the Union army against the Confederacy.

Explanation:

- "the civil rights movements"

- "following the american civil war and abolition of slavery, the united states entered a period known as reconstruction, during which black americans continued to suffer from disenfranchisement, racial segregation, and economic oppression. beginning in the early 1950's, black americans launched a series of major campaigns of civil resistance, emphasizing the need for nonviolent protests and civil disobedience."

"such as the montgomery bus boycott of 1955-56, a campaign launched by rosa parks against the policy of racial segregation of the public transit system in alabama. “sit-ins” became popular across the american south, particularly in greensboro, north carolina, increase national sentiment."

- "the counterculture movement"

- "counterculture began to develop in the united states following the rise of conformity in american culture during the 1950s. by 1963, youth, particularly those of the white middle class, began rejecting the cultural standards and normality of their parents, opting for progressive attitudes instead. the movement gained momentum as the civil rights movement became increasingly successful and as the u.s. military intervention of vietnam began to take a negative turn."

"hippie counterculture moved further into popular culture following the summer of love in 1967 when thousands of people came together in the haight-ashbury neighborhood of san francisco. along with greenwich village in new york city, haight-ashbury became a hub for the counterculture movement."
