how the idea of 750 rifles developed

About the firing squad, Sen McGlinn in one of his comment on Youtube, states:

The idea that the firing squad for the Bab's execution was very large is only found in much later reports. There are contemporary accounts that speak of a small firing squad, even a "platoon," and there are multiple contemporary accounts that say there was a firing squad, with no mention of its size, implying that it was what the observer and his expected reader understood by the term "firing squad." We also have some evidence about how the idea of 750 rifles developed, from bad translations and misunderstandings. This "transmission history" is also positive evidence that would have to be refuted to make a claim of a large firing squad plausible. I have some of the sources online on my Bahai Studies blog, under "750 muskets."

This document contains multiple sources that have narrated the execution of the Bab in chronological order. These include multiple non-Baha'i sources including reports from British and Russian officials and etc. What is obvious, is that the earlier non-Baha'i sources do not mention the fancy miraculous and exaggerated claims that were later fabricated and propagated by Baha'is. It's an interesting document:
