Basically the soldiers waiting for the enemies to push them and start attacking with the Bayonets
Declarative sentence. You are declaring them to look at the water.
In the sentence, "Well, that concludes another very fine experiment", the interjection word would be Well because it shows their expression/feelings as they say it. It could be like, "Oh well" type of way of saying it, or "well this has been fun" type of way.
I know this because interjection is a word that expresses emotion or feelings and is mostly/usually used in the beginning of a sentence.
You're welcome in advanced! I truly hope this helped!
P.S. I put this in my own words.
My grandfather Is CEO of Major businesses, and built a 10 million dollar mansion. His word was so inspiring to me. I said I wanted to do something with my life. Make websites and make money off of them. He said, "Walk instead of talk." Not only was he that kind of man, and I was similarly too. I did do that. Christianmonette.com not exactly selling anything peroid, but I could. I will just design another website because I don't like the website name. Maybe go for a money maker.
So walk instead of talk. Always have to say in a positive way though. He didn't explain that, but others will. Sounds intense, but it is surely something you'd ought' to think about.
