I've got "Breaking the Bismarck Barrier", as well as "Devil boats" and "Operation Cartwheel". The first is too high-level for what I want, the 2nd is naval and the 3rd is air-naval.
I hadn't thought about the ASL scenario pack. I'm not an ASLer, but I have off & on looked into the 37th ID as an Ohioan, so I'll probably try to get that one of these years.
Reading what I have on it, I'm wondering about something with battalion or company counters, perhaps daily turns. Something that would show off the difficulties of jungle fighting and logistics.
I did find a book on Gen. Beightler, the 37th Division's CG, and the Army's longest-serving division commander in the war, as well as one of very few National Guard generals to keep his division into combat and after.
Anyway, the question that continues to bug me: the initial landings were done in 5 separate locations around the island(s), resulting in two land drives against Munda airfield, neither of which had the strength (or organization) to push through without reinforcements. Even then, those reinforcements were taken from different divisions and ad-hoc-ed together. Who planned that initial dispersion and such? Was it a Navy plan, without strong input from an Army staff?
Then, I thought, "this looks like any number of Japanese early-war operations": land here and there, and rely on surprise and fast-moving light infantry to disrupt an unprepared defender. It doesn't work too well when the enemy has a combination of hard fortifications and his own fast-moving light infantry to infiltrate your lines of communications, and isn't surprised.
