Aigle should've seen your planes coming and hung back from yolo'ing the cap.
Your planes were spotted 26 seconds into your replay and you first spotted the Aigle 35 seconds later. That's a lot of time to reconsider hard yolo'ing the cap and seeing what Happy Ending is waiting inside. "We bomb you long time, $5"
Secondly, he smoked and never used it, which was bizarre. However, maybe he was worried he'd be torped out of his smoke by the DD that was firing at him?
Either way, he overcommitted into a known threat and ran out of his only backup plan.
Question to you, can I borrow you for a Training Room? I'd like to run a Tier 6 DD and see how long I can last against you in a Bearn.
