It took a while, but I finally have all 13 of the USS Drum's (SS-228) war patrol reports from WWII online in HTML format:

Take a look over them, it's educational.
While you're there, browse over the entire
Drum228.org website and learn about the past, present, and future of this historic museum submarine!
The USS Drum made a remarkable 13 war patrols in WWII and is the 8th highest in rank of most Japanese tonnage sunk by American submarines in WWII. She was also the FIRST Gato-class submarine commissioned.
