Re: 1965 war...angels?
Just Indians trying to justify why they couldn't beat a smaller army after catching it by surprise ;)
On a more serious note, Allah SWT could make anything happen.
However, bear in mind that many soldiers throughout history make claims of angels. British soldiers after the first major battle against Germany in 1914 at Mons claimed that the Germans were prevented from winning by a line of angels that descenced and fought them off with bows and arrows!
Afer the war, an author later claimed that this was just a rumour based off a story he wrote in which similar events happened, but it's still part of British popular legend to this day.
