Why is such a night selected? Because it makes the dandelions bloom in great numbers.
To what is the coming of the dandelions compared? To an army taking possession of a hill.
What words tell how they came? "Without a sound of warning", "surprised", "We were not waked by bugle notes", "No cheer our dreams invaded".
Explain "surprised the hill". Marched upon it when they were least expected, and seized it.
Give the meaning of "held it in the morning". Had undisputed possession of it.
Tell, in your own words, how the dandelions came. Suddenly and unexpectedly.
How did this attack differ from a real military attack? There were no notes of the bugle or shouts of the soldiers to announce the capture of the hill.
Change "No cheer our dreams invaded" into prose order, and explain the meaning. No cheer invaded our dreams. Our sleep was not disturbed by the victorious shouts of soldiers.
How did the coats of the soldiers you have seen differ in colour from those of the dandelions?
What is the meaning of "at dawn"? The first appearance of light in the morning.
