“After defeating the Djute clan, Roy moved toward Bulgar, the largest city in Sacae. As a center of commerce between Etruria, Bern, and Ilia, Bulgar has had a history of being a free city without a ruler. However, with Bern's invasion, Advisor Roartz now had control of the city under Bern's protection. Roy approached Bulgar to liberate it and to gain some useful information on invading Bern.”
Battle in Bulgar (ブルガルの攻防 Burugaru no Kōbō lit. The Offense and Defense of Bulgar) is Chapter 19B of Fire Emblem: The Binding Blade if you take the Sacaen route (which happens if by the end of Chapter 16, the experience points gained by Sue and Sin were more than or equal to that of Shanna and Thea).
The 5 red houses act like villages and give you the items:
- Turn 8: 4 Nomads from southwest, 4 Dragon Knights from southeast
- Turn 10: 2 Dragon Knights from southeast
- Turn 13: 2 Nomads from southwest
- Turn 15: 2 Dragon Knights from southeast, as well as 4 myrmidons from different houses within the city
- Turn 18: 2 Nomads from southwest
and so on

There are three ways into the city. Two parts of the wall can be broken near the starting location of the enemy Wyvern Riders. If you can quickly dispatch of the small amount of hostile forces outside the gates, breaking these should prove to be the fastest way inside.
It is important to note that most forces inside the city will start moving towards you as soon as an entrance is made, so a highly evasive or defensive unit should be placed at the front of your first entry force. Both walls have 100 health, but using Eclipse can help destroy them in only two attacks.
The enemy Sages hold a Sleep and a Silence staff, so bringing a Restore staff of your own can be beneficial.
The tooltip for the main gate labels it as a Door, but neither thieves nor the Unlock staff can open it. After around 12 turns, however, the gate will be opened, meaning you can sweep the outside enemy reinforcements and bait out the long range spells before this happens. It is possible to have (part of) your forces wait for the gate to open while taking out the enemy reinforcements.
In Turn 13, the boss will order the destruction of the rebel 'villages' inside the walls.
The boss, Gel, is a Sword Master with a Light Brand. If you are worried about his critical strikes, only fight from a distance to remove the risk. Fully abuse both combat triangles against him, using Anima magic from a distance and Spears from up close to increase your accuracy against him. So long as you can hit, he should fall easily.
