This is a great chapter to level up your units because there are A LOT of enemies.
If you like, you can stay at the lower right corner, block the bridges, and let the enemy come to you. Or, send out 3 groups of units and leave Eliwood and others behind to protect Merlinus. If you did send out Merlinus every chapter, then by the start of this chapter, he should be a Transporter, which means he will be able to move around.
Be prepared with healing staffs or items, move one of your group up north where the mounted emeny units are, one northeast where the heavy armored enemy units are, and the last one west to the shops and village.
On turn 8, Vaida will appear, have Eliwood talk to her so she can fight for you.

After you finish this chapter, Eliwood will be automaticly promoted to Knight Lord, even if he's at level 1(but he shouldn't be at level one because the up coming chapter is hard and you can only bring 5 units...)

Boss Strategy:
Lloyd: Lloyd has low defense compare to his resistance, and because he doesn't move, you can surround him with your strong units, and attack at once.
Linus: Linus doesn't move, and has lower resistance than defance, so let magic users attack him from a distance.
