You snooze, you loose. Halo Wars 2 on Fissures

In this 2 vs 2, I was playing Johnson with nolble 3 as Colony. The match started off badly for both of us. We were boxed in and struggling for any territory to boost our economy. It looked like we were doomed to loose the long economic war of attrition. But then... it went quiet. I still don't know why. Were they toying with us? Were they building up? Did the lack the confidence to finish the job? Either way, we had time and we used it. By the time they struck, we were ready. They never expected this reversal.
