Reproduced here is (the text of) a difficult to find and rarely seen errata card for rules updates to the Civil War game published by Avalon Hill in 1961.

IMPORTANT RULE CHANGES — CIVIL WAR

A. PREPARE FOR PLAY: Both Union and Confederate players begin with 6 Pawns each – Confederate, only, may place his pawns adjacent to the North/South border line.

B. RIVER MOVEMENT: Neither player is allowed the additional movement ALONG river lines.

C. HOW TO WIN: Confederate player wins if he: (1) Avoids the Union condition of victory, or (2) Captures any TWO Union replacement centers and retains OCCUPANCY (undisputed control NOT necessary) simultaneously for the two following consecutive months.

While not an accurate simulation, this game provides a nice distraction now and again and frequently finds itself on our game table.
