Sukhdev was hanged on 23 March 1931 in Lahore jail with his friends Rajguru and Bhagat Singh all norms of hanging.
Here are the verses Sukhdev and other revolutionaries died singing:
Watan ki aabru ka pas dekhen kaun karta hai,
Suna hai aaj matkal mein hamara imtihaan hoga;
Shaheedon ki chitaon par judenge har baras mele,
Watan par mitne waalon ka yehi baaki nishan hoga;
Kabhi yeh bhi din ayega jab apna raaj dekhenge,
Jab apni hi zameen hogi aur apna aasmaan hoga.
