Manipulating Garnier

Tannhauser sensed a man who felt that the world had not recognized his quality with sufficient gratitude or honours.
...
"Don't turn around just yet," said Tannhauser. "As the rankers watch us confront each other, we appear to them as giants, making the great decisions that ordain their fate. They're desperate to have faith in in us. They crave it. You are a leader of men. You understand."

Garnier was enthralled. "Faith. They crave it."

"That faith knows no better encouragement than the faith that their captains demonstrate in themselves. And not just in themselves, but in each other. My suggestion is that you clap me on the back and turn to your men with a broad smile on your face - in which expression of camaraderie I'll join you - and they'll see two giants unperturbed by the perils of the world about them, which perils that themselves fear."

As Garnier absorbed this, the smile that grew on his face was not just sincere. He had become Tannhauser's dog and didn't even know it
...
Garneier, buoyed by renewed prestige, gave Tannhauser a formal bow. Tannhauser gritted his teeth and returned it. Garnier's pride was almost pitiful.
