This ambush cave has a narrow and long cavern inside. This is the place which the Katipuneros brought
the Spaniards and killed them. There were several battles happened in
this cave, but instead of killing the Spanish soldier, the Katipuneros
killed the Katipuneros and Spaniards killed the Spaniards because the
place was really dark and they didn't recognized that they were killing
their own group members. More photos, click this link: The Mobile Blogger
