Here is what you need to do to load this scenario:

1. Download or copy CIV2_CW2.zip to a separate (temporary) directory.
Use PKZIP to unpack files.

2. In your Civ II Scenario folder create a new folder called "CW1861" 
and inside CW1861 create a folder called "SOUND" 

3. Copy all the scenario files from the temporary folder into the CW1861
folder, except the nine .wav files which contain the sounds for the new 
units. Copy those nine files into the SOUND sub-folder. (Not the main
"sound" folder).

4. The game.txt file should be moved to the Main Civ II directory, as the
scenario loader does not recognize game.txt files located in the scenario 
subdirectories.  The modifications in this file only involve some minor
text string modifications (Trireme/Coastal vessel, Aircraft/balloon, 
Missile/Torpedo...) that make the game more enjoyable.

5. Start Civ II and select Scenario from the first menu.  The scenario name
is CW1861.  Play Union side at King level to familiarize yourself with
the game features. 
The French, English and Spanish are only trading partners and for the 2 main
civilizations and would be interesting to play only if you want to see what 
would happen if the Confederates got England or France pulled into the War...
