A year, not a day
This entry carries only the year 1862 and the heading “American Civil War” — it appears to be a heading from a chronological list rather than a dated event. No single location, cause or same-day consequence can be assigned to it without inventing one.
What can be documented is the year's shape, and 1862 refuses the usual summary: it contained major Union advances, Confederate victories, inconclusive campaigns, legislation, and a fundamental change in Union war policy.
The river war
On 16 February, Ulysses S. Grant's Union forces secured the surrender of Fort Donelson, opening the Cumberland River to Union operations. On 25 April, David Farragut's fleet reached New Orleans and demanded its surrender; Union control of the lower Mississippi followed.
At Hampton Roads the ironclads USS Monitor and CSS Virginia fought for hours without either ship decisively defeating the other.
Antietam, then emancipation
On 17 September, Union and Confederate armies fought at Antietam near Sharpsburg, Maryland; 22,727 soldiers were killed, wounded or missing, and Lee's first invasion of the North ended when his army withdrew.
Five days later, on 22 September, Lincoln issued the Preliminary Emancipation Proclamation, announcing that enslaved people in areas still in rebellion on 1 January 1863 would be declared free. The final proclamation came on that January date, not in September.
The year did not close in triumph: on 13 December, Confederate forces defeated repeated Union attacks at Fredericksburg, Virginia.

Date disputed. Sources disagree about when this happened.
What the sources leave uncertain
- The record is structurally incomplete: “American Civil War:” appears to be a heading from a chronological list, not an event title.
- Because only a year is supplied, no unique location, immediate cause, or same-day consequence can be assigned without inventing an event.
- This sheet therefore treats 1862 as a year summary. For publication, the record should either be removed or split into separately dated events such as Fort Donelson, New Orleans, Antietam, or the Preliminary Emancipation Proclamation.
