Penang Fire Command consisted of: A Fire Command Post, A Fortress Plotting Room, three Fortress Observation Posts, two Observation Searchlights, a Searchlight Directing Station and three Coast Artillery Batteries, of which only two were armed. It was recorded by Colonel F.W. Rice in his 1946 report,‘Singapore and Penang Coast Artillery’, that there wes no record of the Fortress Plotting Room having been constructed.
Colonel Rice wrote:-
”The batteries are not heavily damaged, but the effort and expense of replacing them is not recommended. It would seem possible that at some future date it might become necessary to institute the Examination Service and in consequence CORNWALLIS Battery which is an integral part of the service should be reconditioned. Both equipments are serviceable though they were removed and were mounted elsewhere by the Japanese. I therefore recommend that these guns be returned to their proper site and instruments and communications provided.”
The Cornwallis Close Defence Battery was armed with two Mark VII 6-Inch BL Guns on Mark II Centre Pivot Mountings. As it was at sea level, the Magazines were of the above ground type. Two 3°CASLs were provided for illuminating targets. The Battery was not spiked when Penang was abandoned in face of the Japanese advance in December 1941. The Japanese took the Battery intact. They later moved one of the guns to Tanjong Pak Pajoh on the south coast of Penang, and the other to Auchry, where it was mounted in the No.2 9·2-Inch Emplacement.

To the right of the BOP is the 1882 Lighthouse, and to the right of that can be seen the walls of fort Cornwallis. Today, nothing remains of the Cornwallis Battery.

Batu Maung was armed with two Mark 24 6-Inch BL Guns on Mark 5 Mountings. As the guns could elevate more than the Mark VII, it had a greater range, 24,500 yards (22,403 metres) compared to the 14,100 yards (12,893 metres) of Cornwallis. This meant that it was classed as a Counter - Bombardment Battery rather than close Defence. Sphinx Battery in Singapore was the only 6-Inch Counter Bombardment Battery there. The remaining 6-Inch Guns were all close Defence. There were plans to add a third Mark 424 6-Inch Gun to the Batu Maung Battery, but the war intervened with the plans.
The Batu Maung guns were successfully spiked in December 1941, but little damage was caused to other elements of the Battery. It was reported in 1946 that, “This battery was little damaged and depredations have been few”. The BOP, Plotting Room, engine room and CASLs were undamaged.

Substantial remains of the Battery exist, and it forms the Penang War Museum.

The Auchry Counter-Bombardment Battery was almost complete in December 1941, but never received the two Mark X 9·2-Inch BL Guns with Mark VII 35° Mountings it was designed for. The guns would have been the same as those mounted at Fort Connaught and Tekong Besar in Singapore. It would seem that no demolitions were carried out to deny the Emplacement to the Japanese.
I believe that there may still be remains of the Battery buried in Auchry Camp.
