Admirals Isoroku Yamamoto and Karl Donitz were hot in discussion regarding the abyssal and the Americans. Both of them wanted to completely defeat the two enemies but knew that they were severely outnumbered in terms of both ships and resources. They needed a plan that could try to negate their weaknesses as best as it could. Hence, they spent hours and hours a day coming up with a suitable strategy to launch a counter-attack.

"Admiral Donitz, I suggest that we launch a surprise attack on the enemy's base," Admiral Yamamoto suggested.

"We could, but we must first find out where their base/bases is/are. If we don't, then our plan will be futile and we will be just wasting resources and maybe even ships," Admiral Donitz said.

"Agreed. That is why I suggest that we send out submarines as a reconnaissance team to find out where their bases are. After that, we can decide on the course of action," Admiral Yamamoto said.

"Fine then, in that case I'll send out 4 submarines. U-510, U511, U-160 and U-161 to locate the enemies' bases," Admiral Donitz said.

"We must also prepare the ships for combat immediately. Then, once we locate the enemies' bases we will launch an attack immediately," Admiral Yamamoto replied.

Admiral Karl Donitz agreed. At 17:00 hours, the 4 submarines were dispatched to find the enemies' base while an announcement was made to prepare for combat.
