Chulau cham

From Terra Nova Wiki

Chulau cham is an island on Earth connected to the mainland via a bridge. Commander Nathaniel Taylor and Lt. Alicia Washington once fought a battle on Chulau cham against a force that was twice as big as theirs. This led them to destroy the bridge to the island, preventing enemy reinforcements from arriving. Wash told Jim Shannon to remind Taylor about Chulau cham, using it as a code that he should destroy the time portal to halt more Phoenix Group mercenaries from invading Terra Nova. (Resistance)
