Battle Of Bessang Pass - March 1944 - June 1944, Phillipines.
There's an oft-overlooked battle in the Pacific theatre of WW2 in the Phillipines called "The Battle Of Bessang Pass" during the Allied liberation of the Phillipines. This battle was something of a tug-of-war between the Filipino Guerillas and the defending Japanese. I'll be using Panzer Campaigns Phillipines '44 to illustrate.
The Bessang Pass was part of a defensive line in the mountains off the west coast of Luzon. It led directly from the coast to the mountainous regions, and so was a key point to the integrity of the defensive line.

Phillipines '44 covers the 3 major parts of the battle over the 4 month period beginning with:
Initial filipino guerilla attack - March 29th 1945

Japanese counter-attack - May 17th 1945

The final push to successfully secure the Bessang Pass - June 10th to June 14th 1945
