Siege of Birtvisi (1403)

[1][2] In medieval Georgia, the fortress Birtvisi entertained a reputation of an impregnable stronghold whose master could control the entire strategic Algeti gorge.

[1] In 1403, Timur sent his vassal, Shah Ibrahim of Shirvan to lead an attack on the fortress.

The defense of the fortress was led by Ivane Toreli, who commanded 150 soldiers in addition to 30 Aznauri and their families.

[4] On 12 August, the gates were stormed by 52 Merkit volunteers who were experts at rock climbing.

The surviving defenders were killed and their wives and children given to Ibrahim's officers.
