Flashback Parallel to current storyline
Flashback
Oden and the Scabbards intended to head for Onigashima to take out Kaido and his forces while they were drunk and had no idea of them coming. This is essentially a raid.
Instead, they meet Kaido in Udon fully prepared with his army to battle Oden and the scabbards. Because of this preparedness Oden and the scabbards are put in a disadvantageous position and the enemy was even able to have the old hag be there prepared to provide support. This causes Oden and the scabbards to lose.
Current Storyline
Samurai-Pirate-Mink Alliance intends to head for Onigashima to take out Kaido and his forces while they are drunk and have no idea of them coming. Again, a raid.
Instead the scabbards arrive in Port Tokage, in Udon with everything they prepared for not in sight and it’s revealed to us that Orochi and his men thwarted the raid and was able to plan ahead. This puts the scabbards in a disadvantageous position and there’s a good chance they lose during the raid.
Take-away
This is the past repeating itself especially for the scabbards. The thing that connects these two failures is the identity of the traitor. The lesson here is the alliance needs to first figure out that they have a traitor and who exactly he/she is. Based on past events, even with a monster like Oden, they have no chance of claiming victory without this knowledge first.

It's definitely the intention of Oda to stress the importance of the traitor.
