@sjelso said in Gibraltar - Does Axis control and closure deny UK of 6 IPC?:

If the Axis control and block Gibraltar does that cut off the 6 IPC from the Mediterranean convoy line?

Are you using optional rule 15.2?
15.2 Suez Re-Route
If Eastern Egypt or Gibraltar is Enemy-possessed, the British IPP in the Meiterranean cannot be the subject of Convoy Raiding. Instead, reassign the British IPP by adding 3 IPPs to the East African Line and 3 IPPs to the West African Line.

If you are not using optional rule 15.2, the 6 IPPs are not “cut-off”, but can easily be raided every turn.
