Information about how to recruit Shamir in Fire Emblem Three Hopes.
In Fire Emblem Three Houses you could recruit many characters simply by getting specific stats and skills high enough. Once done, they’d be impressed enough to realize that studying under you would suit them better than petty considerations such as life-long friendships, national loyalty, familial duty or even religious conviction.
Unfortunately characters in Fire Emblem Three Hopes aren’t quite as malleable - some characters will join your faction as you progress the Main Questline, usually due to story contrivances entirely outside of your control. The rest, however, must be met in battle and “persuaded” to join you… often by lumping them on the head enough times to realize that they’d be better off defecting than decomposing.
Character Recruitment Strategies
In the case where a character can be persuaded to join you, this “persuasion” effort is achieved via the deployment of a Strategy. When you start a battle in which a character can be recruited you’ll first have to pick from a variety of available [Strategies]. You can find more information about Strategies on their own page, but for the purposes of recruiting characters you’ll be interested in any “Persuade [Character]” Strategies, which you must select prior to the battle to ensure you can utilize said Strategy(ies) during the battle. Deploying Strategies in turn require you to expend Strategy Resources, a currency gained by completing [Side Quests] during the chapter leading up to the Main Quest where enemy characters can be recruited.
During battle, when the character you wish to recruit spawns you must activate the Strategy to persuade them by entering the battle menu before you defeat them. If you defeat them without activating the Strategy - even if you selected it before the battle - they will die and you will not be able to recruit that character for the rest of the playthrough! Once the Strategy has been activated, the area where the Strategy is in effect (usually where the target character spawned) will be surrounded by a purple glow. Merely defeat them in this area and you’ll recruit the character.

During the Main Quest in Chapter 9, you will be able to deploy the Persuade Shamir Strategy by expending 20 Strategy Resources. There are no regions to conquer during this chapter, though, but the game does give you 30 Strategy Resources to do with as you wish. Throughout the course of the battle, Shamir will appear to toss a wrench into your plans, but you won’t be able to recruit her during those times. It isn’t until the very end of the mission, once Catherine appears to fight with Edelgard. At this point, Shamir will reappear to join in the fight, and that is when you will be able to initiate the Strategy. However, the key point here is that you simply need to defeat Catherine in order to recruit Shamir, and not Shamir herself.

Shamir will be teased long before she actually appears, courtesy of her companion Catherine. You’ll finally get a chance to recruit Shamir during Chapter 9’s Main Quest battle [Saving of the Silver Maiden]. Despite Shamir’s recruitment being fairly atypical in terms of procedure, you still must deploy the Persuade Shamir Strategy by expending 20 Strategy Resources.
As soon as the battle starts you’ll be tasked with the “Disable the controls in the ramparts and open the main gate” objective, which simply means you need to split your forces and take the Strongholds in the southeastern and southwestern corners of the map. During this you’ll be informed that Shamir is busy fighting just to the north of where you started. Claiming the two aforementioned Strongholds and pulling the levers inside will open the main gate, allowing you to assist Shamir. Activate the “Persaude Shamir” Strategy and defeat the Fortress Knights attacking her to recruit her.
