Question 411 : The Ball's in The British Court.

Right ho!
I found this piece of verse, accompanying the description of an Anglo French Battle.
Shakespeare's a hint.
NOW, WHICH BATTLE IS BEING TALKED ABOUT?
You don't need to id the poet(no points for the poet), but do so if you're feeling generous.
"
'Twas in the year 1415,
That King Henry V and his team,
Crossed the channel and went to France,
To stand firm and defend their stance!
But victory was quite far from their sights,
As they were simply outnumbered by French Knights!

Even the most staunch of believers must think,
That it's time for the British army to sink!
But the Brits did have cause for celebration,
Since the knights were at a greater elevation.

Britain saw discipline as a good omen,
Although just a few hundred Yeomen.
The trumpets sounded,
The battle started!
When the Brits swore by George,
The knights began their charge!

The situation for Henry's men was dire,
With faint hope, the longbowmen fire.
As the French horse received its whip,
Due to wet ground, did it slip!
France, from the jaws of victory, snatched defeat,
Under any circumstances, a remarkable feat.
The Bows observed with glee,
As the remainder of the french army,
Began to flee!

For Britain, a time to revel,
The result, quite a marvel!
With the muddy hill playing spoil sport,
There ended the Battle of ______________
                                                                        "

Question 409: The original Timber-lake

This was a quote from a famous band in a time when music was actually music.
I've removed certain key words, so need to fill in the blanks.
Just id the show

"We were ready to rock out and we waited and waited and finally it was our turn... ...there were____________________ These people were_____ . It was sort of like a painting of a Dante scene, just bodies from hell, all intertwined and asleep, covered with mud.
And this is the moment I will never forget as long as I live: a quarter mile away in the darkness, on the other edge of this bowl, there was some guy flicking his Bic, and in the night I hear, 'Don't worry about it John. We're with you.' I played the rest of the show for that guy."
