Here is a amalgamation of SOPAC Battle Scenarios #2 and #3. It was made possible by ONI documents on the battle.
9 August, 1942
Under direct orders from Admiral Yamamoto a scratch force of cruisers and one DD headed down the slot to contest the USMC landings at Guadalcanal/Tulagi. Spotted by John McCain’s recon they were misidentified as seaplane carriers and considered no threat by Allied command. At 01:43 they opened fire on HMAS Canberra of the Southern Force and ceased fire by 2:30. Two US CA’s sank within the next half-hour, an Aussie scuttled at 0800 and the last US CA sank under tow around noon. Ralph Talbot and Patterson took heavy damage and Chicago lost part of her bow. Damaged Jarvis was sunk by aircraft and Kako was sunk by a US sub on their respective ways home. The US Navy fled later that day leaving only the AP George F Elliot behind still on fire from an early pre-Kamikaze attack on 8/8/42. It sank late on the 9th despite the seven torpedoes Dewey and Hull fired into her just before the Battle of Savo Island began. The Marines ashore were alone.

1. Hex C7 is land (Savo Island). Ships may not enter this hex, no grounding danger on adjacent hexes.
2. Pre battle damage. No VP awarded for this damage.
Jarvis: Torpedoes destroyed, 1 Tertiary, 1 Hull. Speed is reduced to 1+.
Dewey and Hull have expended torpedoes.
3. Start play with impulse 4. The Japanese has initiative and has achieved a surprise starting. Any Allied ship fired on that doesn’t see the shooter is also surprised in subsequent fire phases.
4. IJN ships may exit the map only from Z13 to Z19, US from Z1 to Z4 and Z13.
5. Allied ships may not move until an enemy ship is spotted. Jarvis must exit Z13 and moves in any Speed 1 impulse.
6. IJN DD may drop from formation voluntarily. Japanese forces are in Line Ahead under Optional rule 18.1.
7. Sighting range is 3 hexes for Axis and 1 hex for Allies. Jarvis has no radio and may fire but not spot for Allies. Southern force may fire but may not report sighting. Allied DD’s may not fire unless fired upon.
8. Adm. Crutchley ordered the DD’s to rendezvous with him. On Impulse 1 if US gets initiative all Allied forces are free to move and fight
9. Scenario lasts two Rounds; 41 impulses. On Round 2, Impulse 1; IJN may fight 22 more pulses if retains initiative but must exit the map if Allies gain initiative. IJN may exit the map anytime on Round 1 gaining 2VP’s for each ship exited.
10. IJN must damage all five Allied CA’s of Northern and Southern Force before attacking Tulagi, Guadalcanal or Eastern Forces.
