Units deployed: Corrin, Azura, Felicia, Silas, Effie, Harold, Elise, Owain, Niles, Mozu (reclassed to Archer).
On turn 1 Mozu goes down to Ballista the Oni Savages, gets refreshed by Azura, then shoots them again. Silas pairs up with Harold (strength boost is necessary), then parks in range of two Savages but out of reach of the Ninja. Effie visits the top-right village, Owain magic missiles the Spearmen, Corrin and Felicia follow Silas, Elise heads for the top-left village, and Niles heads towards the top-right corner. Missing either of the ballista shots with Mozu on the leftmost Oni Savage was an automatic reset: Silas needed both to connect to OHKO with Iron Sword (damage on the second Savage is irrelevant since Silas gained the speed point necessary to double after leveling up from killing the first).
Turn 2 Felicia attacks the surviving Oni Chieftain, putting him in KO range for Corrin's Dragonstone. Silas then OHKOes the Ninja with Iron Lance, just barely in Oboro's range thanks to her Lunatic +1 Movement skill. Mozu shoots the cluster of Ninjas and Spearmen, then gets refreshed by Azura (who is now in range of a Pegasus Knight) and moves out of the Ninjas' attack range. Mozu is now positioned so that she can both support Severa in Attack Stance next turn after the Pegasus Knight attacks Azura, and be ready for Camilla to pair up with her so that Camilla can reach a Ninja next turn. Elise grabs 10k gold, Owain shoots the Savages on the left of the map (as long as the surviving Spearman near the house is at 13 HP or less; otherwise Owain has to shoot him to ensure Beruka can KO next turn), and Effie pairs up with Niles, who parks in range of the archers on the right. Oboro's attack on Silas is blocked by Guard Stance, she takes half her health in damage, and Silas becomes temporarily gimped. A Spearman suicides on Corrin, and the Archers suicide on Niles (usually. Sometimes Niles misses his one of his two attacks, in which case he'll retreat to use the Ballista on the Spearmen and rely on Guard Stance to survive the Archers attacking him again). Both of the partitions get broken.
Turn 3: Silas moves over to the closest Ninja on the left and Harold attacks him (sometimes Harold gets to use Iron Axe, sometimes he has to rely on sub-70% accuracy with his Hand Axe because of the Ninja's positioning. Either way, it's dicey and entirely dependent on Mozu having hit that group with the Ballista, which she usually does). Afterwards Corrin KOes Oboro with Dragonstone. Either of these attacks missing prompts a reset. Severa moves next to Mozu, takes the Brass Naginata and Heart Seal Mozu is holding, gives her her Vulnerary for Camilla to use later, then KOes the Pegasus Knight Azura damaged last turn (Bronze Sword + Mozu's Attack Stance support is a guaranteed kill). Beruka kills the surviving Spearman, then Camilla pairs with Mozu, who moves down and switches back to Camilla, who Lunges and OHKOes the last Ninja (Lunge gives Azura a space to refresh Camilla). Camilla does NOT visit the village after being refreshed, but instead zips down towards the left boat, as she is going to be the one taking down Takumi. That's right, a flying unit is going to best the wielder of the Fujin Yumi. Effie pulls back so that she's just inside the Spearman's attack range (going to attack him directly means that Niles won't make it in time to snipe a Pegasus Knight that breaks through the line, and Effie is in no danger doing this since she can afford to tank a few extra hits on account of being bulky as fuck). Elise gets close to Owain, who fireballs the Savages again. Corrin brings two Oni Savages down to 1 HP, levels up, the OHKOes the final Savage on account of the magic point he gained.
Around here the specifics break down to a blur. By this point I had the first three turns down to a science, but beyond that tended to be uncharted territory. In broad strokes, Camilla picked off enemies on the left boat, being careful not to enter the range of Takumi, Hinata, or Ninjas. Once her Guard Guage was filled (not in time to prevent Dragon Vein usage, thanks to a cowardly Spearman refusing to suicide on her), she parked behind Takumi and shipped turn without attacking. Takumi immediately attacks, has his shot blocked, then takes 23 from Camilla's Steel Axe. Next turn Camilla attacks Takumi with Steel Axe and KOes. It took two 63% hits to do it, but it finally worked. Afterwards Camilla just barely keeps herself out of Ninja range and bitch-slaps Hinata with Thunder before flying back to the defend point towards the last turns of the map, providing invaluable OHKOes along the way.
While this is going on, Corrin moves to just outside Ninja range, uses a Concoction to return to full health, and KOes the remaining Savages and a Pegasus Knight or two on enemy phase. Everyone moves out of range of the Ninjas and the Spearman with Attack Seal, Owain KOes a Savage with Thunder then a second on enemy phase, Effie cleans up the second Spearman on enemy phase. Severa reclasses into Pegasus Knight while Elise does a little bit of healing. Next turn Corrin KOes a Ninja with Dragonstone, Owain weakens the Spearman and Ninja with a fireball, then Silas kills the Ninja with Iron Lance while Beruka cleans up the Spearman. At some point after this Beruka nabs the Dual Club. After all this Corrin heads towards the righthand village while everyone else pulls back and focuses on defense. Things get dicey during the last few turns as they tend to during the last few turns of the map (Corrin is facing down two Savages and a Ninja at 9 HP with no Concoction uses left, Niles nearly dies going up against the three Archers who commandeer the right ballista, etc.). Three Freeze staff uses are expended in the last few turns; one or two of them might have been extraneous, but there was no fucking chance I was gambling on enemy AI prioritizing getting to the safe zone over attacking weakened units at this point. The relief I felt on the last turn when I realized that all I had to do was move my units (excluding Camilla and Niles, who were in no danger of being KOed) was enormous.
