What does 收 mean in 他把何进部下的兵都收归己有? This is from near the  beginning of 三国演义 and I am already puzzled：

他把何进部下的兵都收归己有。 Maybe: He （收？) recaptured / imprisoned all the troops under 何进's command 

归己有： returned them to his own command ??

收 is '收复‘ or '收监‘ or some other word？

[3] belong to; rest with; be in charge

己= self
有= possession
收歸己有 = &quot;take possession and make it belong to oneself&quot;
There's a common phrase &quot;收歸國有&quot;, which means &quot;Take possession (of a company) and assign it to become State-owned &quot; . Similarly &quot;收歸己有&quot; in your sentence would mean : &quot;&quot;Take possession (of an army) and assign it to become Self-owned &quot;
