I just got really excited
I had already surveyed this system a long time ago and only found two jump points. A while back a few ships from The Sad Confederation (I did not name them) arrived in Gypsum, a system under my control, but they came from a direction I had not expected. Or rather, it seemed impossible that they would have been able to get there without being discovered by any of my sensors along the way.
I knew that Alluyen, the system of The Sad Confederation, had two unexplored jump points, which I had not been able to explore because they have parked their entire fleet at the Charis jump point, my only access to their system, which had previous caused me massive losses.
I started to suspect that there might be an undiscovered jump point in a previously surveyed system. Instead of completely wiping out all of the ships that arrived in Gypsum, I sent most of the fleet home to conserve fuel, which is a real problem right now, and ordered a small squadron to follow the remaining two ships as they were retreating. We followed them to Lancaster at a distance of 450 million km, and saw them jump through to Parakoila. As we squadron jumped through and spotted them on the active sensor, they started heading towards us. We had no choice but to shoot them down.
The lead had turned cold, but as soon as a survey ship was ready I sent them to Parakoila to conduct a new survey. With the above result. There is a good chance I have found a back entrance into Alluyen, which means I can actually fight their fleet without worrying about transit delay, which destroyed my fleet last time. Now I only need to send a scout in to figure out which jump point it leads to or if there is any systems between us.
Having to use actual tactics like these is part of what makes this game awesome.
