What is the meaning of Moonligth in manila Bay By fernando Maramag?

It is about Manila Bay Battle 1898. Manila Bay then was a serene place. The ambiance of the bay was so peaceful that one could see the reflection of the moonlight on the water. The water was placid, the place was unharmed and the people were untroubled. They were living a passive life then. In this poem, Maramag is expressing what he felt during war.
