Here is an article I found on the web. To tell you the truth, the article's facts are outdated.
You know my position on the Battle of Nagashino. I am more than willing to accept the new data if the number of troops support it. If Owada Tetsuo is correct on numbers Oda/Tokugawa 18,000 and the Takeda 6,000. Then by all means, history has been changed. If Nobunaga had an army of 10,000, 1,000 gunners would be acceptable. The more I see the new data in books and magazine, the more quickly it is being accepted. However, the number of guns used at the battle should be continued to be debated. Nobody really knows how many guns were used at the battle.
One thing is a fact, not many people are making a trip to the battlefield. People should visit the place and check out the battlefield's geography. As for the SA, they are sticking with the new data. There are two historians I have great respect for, Owada Tetsuo and Paul Varley. When you read their work on Nagashino, they are not taking away the fact guns played a huge role in the battle. Their focus was the amount of guns used, geography, and tactics.
Nobunaga no Tame!
