Info or books on Persian Gulf/Bahrain in Hellenistic time frame?

[Marcus Cassius LegioXIV]

So just moved to Bahrain and found that the Greeks seemed to be rather active here and a good possibility of a Seleucid troops being here. 

 Any books people can suggest on Greek influence on the Persian gulf? Anything on campaigns through here or types of troops used too? 

Thanks for any help!
