addition to protect the original inner Gate
When I was in School ( PPS ) , in late 1960 s / early 1970 s I visited the Red Fort , Delhi. From the outer Lahore Gate ( i.e. the Main Gate - Barbican ) , turning 90 o left is the original Lahore Gate.
At this gate on the Left , there is a narrow stair case leading to a floor where there were piled numerous muzzle loading rifles / guns which were seized by the victorious Britishers from Indian rebels / mutineers in 1857 /1858 and stored in Red Fort.
Apart from the patriotic value , such rifles gradually became antiques commanding immense value among collectors.
When I was in College ( St. Stephen's College Delhi ) in mid and late 1970 s, I , again visited the Red Fort and made straight for the room / hall which had earlier housed the then prize less and venerable ( for us ) rifles.
To my utter surprise there was not a single rifle there !!
Thinking these might have been shifted , I made inquiries. But no body could tell me where they went. They said they did not know .
