After Tahmasp Khan Jalayer engaged and routed a joint Ottoman and Crimean Tatar force in the south east Caucasus Nader cut their line of retreat further west dealing them another crippling blow, scattering them into the mountains north.
The mountains to the north in Avarestan made any pursuit of the defeated foe a daunting prospect especially considering the approach of winter, so Nader chose to turn west and besiege Ganja where he was drawn into an intense effort to capture the surprisingly formidable fortress.
The Persian artillery was still severely lacking in strong siege guns and consisted mostly of field batteries which were effective in battles but unable to make significant impact against city walls and battlements.
Failing in their siege artillery capacity the Persian sent sappers to dig underground to reach the citadels walls from beneath but the Turks received timely intelligence reports revealing the intention of the besiegers.
The crushing defeat at Baghavard also provided sufficient persuasion to retreat for the 50,000 Crimean Tatars who were commanded by the Turkish Sultan to march south along the coast of the Black Sea ([citation needed][4]) descending down into the Caucasus in order to aid Koprulu Pasha's forces.
