At Independence or the Partition  about 10 lac Punjabi followers of Nanak were massacred. How could Nanak remain unaffected? Again Nanak stood in between the warring  communities.  Kartarpur story is full of miracles. Those blindings, skeletons, flowers and sheet and what not. On June 6, 1947 whole of district of Gurdaspur was allotted to Pakistan. But this plan was not acceptable and Partition process was still incomplete.  But again a miracle happened.  Redcliffe now drew his fresh boundary line bisecting Gurdaspur right across the chest of Kartarpur: the site proper going to Muslims of Pakistan and land of Baba Nanak falling in this side of river i.e towards of Hindus and Sikhs. How could Nanak remain exclusively on one side.
For 52 long years, Sikhs have been ignoring it because it stands on the other side of the cruel border. There are reports that some Sikhs of nearby villages visited Kartarpur stealthily in the nights.
Things have however become impossible with India converting the borderline of an impregnable barbed wire.
Notwithstanding, Sikhs didn’t make any serious effort to keep paying their obeisance. There were many alternatives like:
  [i]Requesting the Govt of Pakistan to gift the small area to Sikhs of India. After all the shrine is only about 2 Kms inside the border.
  [ii] Asking Pakistan for exchange of territory. There are many inconvenient areas of India which lie beyond river Ravi. Even there are many Sikhs to donate their lands in lieu of exchange for Kartarpur.
  [iii] Offering payment to Pakistan for the appropriate area, which they might not accept as it would have been a small amount for a big country.
  [iv] Requesting Pakistan to allow unrestricted entry of Sikhs on certain days. Like there exists a practice in Khemkaran sector where tomb of Muslim fakir Sheikh Braham, a contemporary of Nanak is being visited by Muslims across the border. Similarly at Chamliyal near R.S.Pura in Jammu Govt of India allows entry without any passport or visa
