Re: U-Boat victories and claims

Hello Adriano and all,
British Naval Intelligence relied very heavily on D/F (direction finding) and T/A (traffic analysis) to maintain their OIC (Operational Intelligence Centre) maps. These maps were extraordinarily accurate even during the ‘blackout’ caused by the introduction of the fourth wheel. The OIC situation reports and Naval Intelligence Summaries were constantly updated and it was from these that victories were credited.

Hope this helps,
Bruce
