From the Puffer

Depth charged by Chidori Class torpedo boat while at deep submergence. Second escort later joined attack. Depth charging extended over 14 hour period and Puffer was then tracked for an additional 12 hours by the enemy vessel. Engine air induction and ship's supply ventilation outboard valve gaskets were blown out, allowing both systems to completely flood. All deck hatches, conning tower door and forward escape trunk door fluttered on each close depth charge and leaked continuously thereafter. Boat became heavy overall, principally due to flooding mentioned above. Depth control was maintained by running at slow speed with a 12° up angle and by gradually blowing negative safety, auxiliary and after trim tanks.Boat reached 500 foot maximum depth. All bilges flooded. Trim pump (reciprocating type) was too noisy to permit its use Rudder and stern planes developed high noise level, apparently due to misalignment. Leakage developed at external piping silver soldered joints of No. 4 air bank,. Radio antenna trunk flooded. Plug for previously removed sea pressure gauge line in maneuvering room water closet sea valve backed out, allowing considerable water to enter after torpedo room. Flanged joint of trim line ruptured in after torpedo room. Both JK-QC and QB sound training motors were grounded by flooding and both sound head shafts were slightly misaligned. No. 1 air conditioning circulating water pump motor grounded due to flooding. Brushes were jarred loose on Nos. 1 and 2 lighting motor generators. gyro spindles inside boat increased to six pounds above atmospheric, air temperature reached 125° F. and co2 content increased considerably, causing much discomfort to all hands. Numerous light bulbs, gauges and instruments were broken or deranged and much other minor damage occurred. Dive lasted 38 hours, Ship terminated patrol.
