Which of the following is not one of the union generals who lincoln fired:

(b)"stonewall" jackson
(c)ambrose burnside
(d)joseph ho0ker

The correct answer is:  

(B)"Stonewall" Jackson.

Thomas Jonathan "Stonewall" Jackson (January 21, 1824 – May 10, 1863) served as a Confederate general (1861–1863) during the American Civil War, and became one of the best-known Confederate commanders.

In the spring of 1862, Jackson spearheaded the Shenandoah Valley Campaign, firmly establishing himself as a strong and independent commander. He earned the admiration of Union generals and had become the South’s first great war hero. Jackson had prevented the Northerners from taking the Confederate capital of Richmond, Virginia.

"germany's geographic location was an advantage when it was on the offensive in the war because it was situated next to an extremely wide river, the rhine, which was difficult for the allies to cross."
