Zg644. This is a US Army project completion report 20th June 1932 of the completion of a Fresh Water Storage Dam in the Calumpang Reservation for Fort Frank; with a picture of the dam zoomed in.
With fuel stocks running low a new attempt was made on March 9 to repair the water line. Under cover of a barrage of shells from the 75mm guns a party landed on the mainland and after nine hours repaired the break. Amazingly, the Japanese did not interfere with the repair of the waterpipe though it lay on ground they occupied. For the remainder of March, Fort Frank was to have ample water.
The first part of March saw the 75mm guns firing numerous rounds of shrapnel at enemy concentrations while Battery Frank North struck at supposed Japanese gun positions. The enemy reply to these shots was feeble or non-existent. This, however changed on March 15 when the Hayakawa detachment’s two 240mm howitzers opened fire on Forts Frank and Drum. At this same time 155mm guns also hit Mills and Hughes. Hardest hit was Fort Frank which lost two guns each at Batteries Frank North and Ermita to direct hits, plus repairable damages to the other guns of these batteries. Also destroyed was a machine gun post, while Battery Koehler had seven of its mortars damaged. In all more than 500 shells hit Fort Frank this day.
