So far I have come up with this:
El 29 de Julio emprendió la marcha para Barcelona con objeto de prestar el servicio de concentración por orden de xxx el Director General del Cuerpo en telegrama fecha 27 del expresado mes.
Thank you in advance for you help in transcribing this document.
Update 1
I have updated the text to include @SergioVelasquez suggestions and I adjusted en telegrama.
Update 2
Added the word expresado and updated the translation.
Translation
