Islamic Scholar Needed—Blood Consumption Ruling & Historical Sources

⚠️Content Warning⚠️ Is licking blood considered haram in Islam? Looking for sources for historical research l. Hi everyone, I’m doing some historical research on the punishments used during the 1857 Indian National Revolt. One British officer (General James George Smith Neill) reportedly forced condemned prisoners (they killed European women and children, which triggered the Racist British People who held a sense of white cultural superiority at the time), some of whom were Muslim, to lick blood from a slaughterhouse floor before being executed. The following is a statement of events by Forbes-Mitchell, a soldier serving in the 93rd Sutherland Highlanders in 1857: >! “Up to the date of my visit, a brigade-order, issued by Brigadier-General J. G. S. Neill, First Madras Fusiliers, was still in force. This order bears date the 25th of July, 1857. I have not now an exact copy of it, but its purport was to this effect: That, after trial and condemnation, all prisoners found guilty of having taken part in the murder of the European women and children, were to be taken into the slaughter-house by Major Bruce's mehter police, and there made to crouch down, and with their mouths lick clean a square foot of the blood-soaked floor before being taken to the gallows and hanged. This order was carried out in my presence as regards the three wretches who were hanged that morning. The dried blood on the floor was first moistened with water, and the lash of the warder was applied till the wretches kneelèd down and cleaned their square foot of flooring.” !< William Forbes-Mitchell, Reminiscences of the Great Mutiny 1857-59, 19-20 For my research, I need to understand how this action would be viewed in Islamic law. My questions are: Is consuming or licking blood considered haram in Islam? Is it possible to explain which Islamic texts (Qur’an verses, hadith, or fiqh rules) forbid the consumption of blood? If you can, could you direct me to specific citations or scholarly interpretations that I can reference, Please? There's another question, and I'm not sure if it will be controversial. I've heard that if a believer is accidentally given blood, it's not considered a violation of the religious doctrine. So I'm wondering if these Muslim sepoy will be pardoned? Even if the Muslim sepoys are forgiven, what are your thoughts on General Neill's atrocities aginst their Islamic beliefs? I know this piece of history may make people uncomfortable, and I want to clarify that I am not promoting imperialism. The reason I’m asking you is because I’ve been writing an essay debunking the myths about a military figure. The actions of the one in the source above and the one whose the myths of him are going to be debunked by me are often confused, because people rarely do careful research and instead spread rumours irresponsibly. I want to clarify that the one who has myths surroundwd did not support this kind of atrocity that humiliates the enemy’s religious beliefs. I know that the audience I will be facing in the future may not necessarily understand Islam, so I would like to cite some sources to make my arguments more persuasive. Any help would be greatly appreciated
