Pop star Phil Collins has handed over his vast collection of artefacts related to the Battle of the Alamo and the Texas Revolution to the state of Texas.

Collins was in San Antonio to donate what is considered to be the world's largest private collection of Alamo artefacts.

It includes a fringed leather pouch and a gun used by Davy Crockett and Jim Bowie's legendary knife.

The 1980s pop star and Genesis singer-drummer has joked that he spent all the money he had made from music on artefacts related to the 1836 battle where 1,500 Mexican troops laid siege to 200 Texans.

The collection was given to Texas land commissioner Jerry Patterson, the state steward of the Alamo. He is pushing for a new Alamo historical centre that would house Collins' collection.
