BATTERY GRAIGHILL

(Pit A)

Heavy Seacoast Gun (Fixed Emplacement)

Lower Pit - Two 12-inch Mortar M1912 on 12-inch Mortar Carriage M1896M3. The Pit B (Upper) mortars are buried, making them look like the older  models.  But they are M1912 whose barrels are 50% longer than those found at Battery Way and Geary Pit A.

Ft. Hughes, Caballo Island  - photo essay by Tony Feredo

If you follow the designation system adopted for Fort Mills and the other islands, the upper Pit should be Pit A and the lower should be Pit B, (right to left).  However, originally, Battery Craighill was intended to be two separate semi independent  batteries, ... From a firing baseline of these pits  wherein it labeled TAC Battery 11 (Craighill B) and TAC Battery 12 (Craighill A) and the rear of this batteries are not the railway path but from the battery plotting room at the rear of mortars pits.  the lower (eastern)  Pit is A and the upper (western) is Pit B  I have a longer explanation but it will just bore you with all those coast artillery lingo .....  So in some references (i.e. Charles Small:  Rails to Doomsday,  he labeled the upper Pit as A and the lower Pit as B which is wrong.)  - Tony Feredo
