Final answer:
Lincoln did not announce the war was to free the enslaved at its outbreak; initially, he focused on preserving the Union and made the abolition of slavery a war aim later with the Emancipation Proclamation.
Step-by-step explanation:
Based on the preface concerning Abraham Lincoln, it is not true that Lincoln announced the Civil War was being fought to free those enslaved in the South when the war broke out. At that time, Lincoln's focus was on preserving the Union and he explicitly noted he would not interfere with slavery where it already existed. His inaugural address made no mention of ending slavery but instead emphasized the permanent nature of the Union and a plea for reconciliation amongst divided Americans. It was only later, with the Emancipation Proclamation in 1863, that Lincoln would make the abolition of slavery a central war aim.
