This was an initially interesting scenario that started to drag a bit because of the combined night/jungle environment. About a regiment of Japanese are trying to get past about a reinforced battalion of Marines dug in on the eponymous ridge, surrounded by jungle. The Marines want to keep Japanese units from exiting.

What makes the scenario kind of cool is the disorientation that effects the Japanese. Combined with the 1-hex visibility and the Guadalcanal night fog of war number (14!) this made it incredibly slow going for all of these Japanese stacks to get anywhere. The Marines sought to engage the Japanese as they got close to the ridge, since the Japanese Banzai rule prevents them from leaving assault hexes.

The Japanese tried to keep their forces together, but the disorientation rule says that you roll for each unit that moves, not each stack (PG units move individually, especially for opp. fire), so a company of Japanese might end up scattering in three directions in the Jungle. The Marines weren't affected by disorientation, so they could keep their stacks together, and they needed all that firepower to assault even a single Japanese platoon in the jungle. First fire and Japanese assault bonus are tough.

Even with this headwind, they managed to cause enough step losses to the Marines to fulfill one victory condition, but after 5 hours they had only managed to exit a half platoon, so it was a draw. Seemed pretty balanced though, so not a bad scenario.
