There aren't any reinforcements on this map, so there's no rush. Feel free to slowly bait enemies one at a time by plinking them with Curved Shot then retreating, or putting one tank in their threat range. Additionally, there's not really much advantage to pulling the levers; the trap floors impede enemy mobility as well, and make it easier for long-range mages and archers to shoot down Kingdom forces on the other side safely. Don't feel obligated to have your right-side 3 units actually charge in to the fortress; they can also head south and join up with your main team if you'd prefer to keep your forces concentrated.
The most threatening turns are arguably the first two, where Felix and Rodrigue and their friends will come charging out of the gate at you. Rodrigue packs mixed damage off both Aura and a Silver Lance, so be careful who you leave in his impressive threat range; squishy mages like Linhardt will just be impaled by his Silver Lance. For Felix and the Fortress Knights, magic damage is recommended; if you can't finish them quickly enough, Bernadetta's Encloser will freeze them in place so that you can avoid eating their impressive offense. Gwendal can be baited by sticking a unit in range of his Pegasus Knight; then destroyed by any sort of magic damage. Ingrid is scary, with 52+6 speed on initiation in Maddening mode thanks to Darting Blow; the Impregnable Wall gambit is, as usual, the safest way to bait her forward. You can also set up for a lethal bow counter OHKO if you have a strong enough archer. Cornelia won't move, so you can plink her to death with Curved Shots or other long-range Bow combat arts until you have a fatal OHKO ready.
Be sure to fully shield break at least one of the Titanus's if you've been using Edelgard's Raging Storm; they drop the extremely rare Agarthium, which is needed to repair Aymr, Edelgard's axe.
