How did President Abraham Lincoln attempt to silence criticism of the US Civil War?

President Lincoln's conduct during the US Civil War was under constant scrutiny. In the North he had to suspend habeas corpus to silence Southern sympathizers. He used military force to stop draft riots and some newspapers critical of the war were put under pressure to not criticize his war efforts. The radical wing of the Republican Party quickly formed the Joint Committee on the Conduct of the War as they believed Lincoln was too soft on dissenters and War Democrats were also critical of his methods. Maryland dissenters faced military action, while abolitionist newspapers believed Lincoln was not more vocal on slavery. The military officers were also unhappy and even Union General Joseph Hooker spoke openly to Lincoln about a military coup. In January of 1863, the governor of Indiana was threatening to form his own peace treaty with the South.Lincoln was under immense pressure. He even spoke about his own possible assassination. He was not even sure in the Summer of 1864 if his own party was going to nominate him for the presidency.

Somehow Lincoln persevered despite all attempts to make his administration unstable, including the resignation of Salmon Chase.
