you won't hear it when you are playing on the american side, the diving too deep voices only come about when you are reaching 200 meters or more, and since american subs can't go that deep, you won't hear them

yep, some sounds are bugged in the sh.sdl file or something. (like the famous "rudder rudder" repeated sound error)

my mod replaces the missing sound files but it doesnt make the sounds work any better.

some sounds work sometimes but not every time and some sounds dont work at all but i never dug into the control of the sounds i only found sounds that didnt have a sound file for them and i gave them a sound file.

i was always wanting to learn more about how the sounds worked to fix them but i never got the time.

oh, ok

sailor steve - graf spee
 

I have had an interest in the graf spee story for years. There is a great account of it on wikipedia. Recently, it was discouvered that had the Graf Spee continued to battle it would have run out of fuel in just a couple of hours due to battle damage. That may be why the Exeter was not sunk when it was vulnerable. The chase to Mondevideo lasted most of the day. The Brits falsely claimed that several battleships were on their way to support the Ajax and Achilles to pressure the Uraguan government to order the Graf Spee to depart.

The story I like, which may or may not be true, is this. As the
Ajax, Achilles and Graf Spee approached the River Platte, one of the British warships shadowing the Graf Spee moved close to shore. The Graf Spee was to its east. The sun was setting behind the British warship, i.e to the west, and its rays were reflecting off the Graf Spee's hull, illuninating it as a target. Meanwhile the attacking cruiser could not be seen as it was sitting in the center of the view of the sun and obscured by the shadows from the land. Now, that is my idea of batle tactics! I read an article in the NYT written in 1939 that provided that account.
