- "The 1st Tapani Assault Battlegroup has filled this role with distinction, notching Imperial victories during the Rout of Spuma and the Humiliation of Barkhesh."
"Not how I remember it. The 1st Tapani withdrew from Barkhesh after losing a fifth of its troopers in an acidic hailstorm."
- ―The competing testimonies of Cassio Tagge and Carlist Rieekan, Imperial Handbook: A Commander's Guide
The Humiliation of Barkhesh was a Galactic Civil War engagement on the planet Barkhesh between the Galactic Empire and Rebel Alliance sometime before the Battle of Yavin. According to Imperial Army High General Cassio Tagge in contributing to the Imperial Handbook: A Commander's Guide, the 1st Tapani Assault Battlegroup triumphed in the battle, a claim later refuted by Rebel General Carlist Rieekan.
