Ignore the Indians, posting without knowing a single thing. That checkpost in border was in East pakistan. But it was captured by Muktis and was used as training camp under Indian Army! Later after independence, india didn't vacate it. In 2001, BSF started to construct a road there, BDR protested and captured the post.
Any Bangladeshi who has Army friends ask them, its a open secret that more than 100 indians died that night. But India could do nothing as Hasina was in power, they concealed it from indians to avoid public anger!
