Pink house on No1 is where I am currently sitting posting this, Corrigedor Island was where the last stand was made in The Philippines, there were a chain of forts accross Manila Bay which I think would have been effective if the Japanes came that way but like Singapore the landed elswhere and came overland down the Bataan Peninsular and around Cavite.
Caballo Island next to Corrigedor was also fortified. the concrete battle ship was a smal island till the Spanish during the time they ruled here cut the above sea level top off and built a ship shaped fort on it, its last armament was 4 x 14" guns in 2 turrets, still there today.
Fort Frank was easier to take since it was a island a couple of hundred yards off shore who's water supply was piped from the mainland the Japanese cut the water supply.
Sangley point is the airfield to the left of Ark V.
The Bataan death march for some started in Corrigedor up the peninsular to Fort Santiago in Intramuros the old Spanish Citadel on the River Passig in Manila.
Taal Lake and Volcano is just right of centre at the bottom of Google 1 as is Fernando airbase, the lake I think you were talking about is Laguna De Bay, it is not clear on the Google but is in the grey area under the name Cora's house and extends down to the light blue area.
Subic Bay at top left I suspect you know a bit about.
Hope this helps
