The Retreat's supplies are a miscellaneous quest item in the Fallout 76 update Steel Dawn.
This is a collection of supplies belonging to the Retreat that have been extorted from them by the Blood Eagles led by Dagger.
Can be retrieved at the end of Disarming Discovery after killing Dagger or convincing her to relinquish the supplies. The item is in a wooden crate in the Dagger's Den throne room.
