Ah, okay. Still, by this point Britain will likely be in Sirte, so I imagine Germany would struggle to make any use of it.It was NOT British codes that were broken
but a US diplomatic code used by the American military attache to send his summaries of the briefing he received to Wahington
That gave the Fascista a full DAILY strategic breakdown - including all men and equipment numbers
as well as his very pessimistic opinions of British plans
However @Cryhavoc101 is also correct that lax tactical comms by British troops gave away some very useful but more localised info.
