Opinions on what I should do?

[Zero Niner]

It's Sept/Oct 1943 and I'm patrolling off the Palau Islands when radar picks up a convoy heading NW.

I intercept and manage to sink 2 merchants. However in the ensuing counter attack I suffer quite a bit of damage from depth charges - bulkhead, batteries, torp tubes, heavy flooding in the aft torpedo room, prop shafts, rudder... At one point it was all I could do to keep the sub from sinking. Heh, at one point the bow was pointing up whilst the sub was sinking lower. I could only maintain depth with a speed of at least 3 knots and I had to keep ordering the sub to surface. Coulnd't order silent running or slow speeds obviously.

After about 4 hours (game time) of pasting the escorts gave up and moved away. I surfaced and finished off whatever repairs I could. However I've a number of equipment damaged beyond repair - all the stern torp tubes, the stern dive planes, and one bow torpedo tube.

I headed for Darwin hoping that I could get these repaired but alas no. So now I have a damaged sub, and I'm wondering should I carry on with the patrol or head for Midway with 4 objectives completed but only 2 ships to show for this patrol.

Your thoughts? Hull integrity is still at 100%, crew healthy, all systems working fine except for what I mentioned above. Due to the damage to the torp tubes I have effectively 15 torpedos to expend (5 in the bow, 10 reloads).
