which method of communication did president Lincoln use the most to inform the public about the civil war?

the telegraph and announcements

explanations:

the telegraph: was used heavily by the press during the Civil War, had a long-lasting effect on journalism. with a lack of guidelines on how the military would work with the press, both union and confederate governments and armies restricted reporting and closed newspapers, causing tension with the press.

anouncements: on january 1, 1863, lincoln issued the final emancipation proclamation, which declared “that all persons held as slaves” within the rebel states “are, and henceforward shall be free.” the proclamation also called for the recruitment and establishment of black military units among the union forces.

lincoln's 1863 emancipation proclamation freed about 20,000 of slaves in confederate-held territory, and established emancipation as a union war goal. in 1865, lincoln was instrumental in the passage of the thirteenth amendment, which made slavery unconstitutional.
