Upon reunification and during the course of Je’She’s first campaigns, the primarch began to modify his legion’s organisation. Keeping the majority of the original structure, he did however put immense efforts into changing the culture and mindset of his legion, instilling values of stoicism and humanity into his legionnaires. He encouraged creative pursuits, reasoning that a good warrior is a well-rounded warrior. 
Before long, the Sentinels were nearly unrecognisable from their fanatical origins. No longer was the fire unchecked, not locked away, but merely redirected towards different goals. The IXth became known for surviving against the odds, holding the lines until their enemy broke themselves attempting to break through. Siege masters with few equals, they ground down fortresses and rebuilt them even greater. They showed mercy when necessary, but left nought but rubble when they had to, and in their wake left cities even greater than their forebears.

Under the leadership of Je'She, the IXth distinguished themselves as prime examples of the Crusade's ideals. They were relentless in their drive to reunite humanity. They're initial diplomatic approach was received mixed approval from other legions, but proved to be an effective course of action in many cases. However, their military record was as long and prestigious as any other legion. While they did not bring worlds to compliance as fast as other legions, such as the [[Emperor's Dragoons]] or [[Silver Blades]], they were noted for leaving behind worlds in much further stages of reconstruction and compliance. Noted for their humanity and selflessness, they became well loved throughout the Imperium. Their campaigns spread across the galaxy from the Segmentum Obscurus, across the Ultima Segmentum, and into the fringes of the Segmentum Tempestus. Their expertise in defenses and siege warfare lent them an edge in taking civilized or warlike empires. Breaking through every weak spot and exploiting every mistake in the enemy's defenses with deadly tenacity. 

The Sentinels fought with most of their brother legions throughout the Great Crusade. They forged strong ties with many of them, especially the [[Silver Blades]], [[Titan Marchers]], [[Emperor's Dragoons]], [[Loxodontii]], [[Golden Mountains]] and [[Chosen of Hecate]]. Their infantry based tactics allowed them to work well with other legions in whatever position necessary. In the latter days of the Great Crusade, many warhosts were pulled back from the front to man the Imperial Ring, a blockade of fortress worlds around the edges of the Segmentum Solar. The intention was reinforce the Imperial territories and in extent, protect the Emperor interred upon the Golden Throne after Ullanor. However, this was perceived by certain legions as a power play to consolidate control over worlds critical to the Imperium of Man. This aided in an already rising of tensions between legions and Primarchs.
