This might be a double definition.

'frustrate' is the first definition.
(I know that dash is a more specific form of the action frustrate)

'a fleet movement' is the second definition.
'dash' can be an answer for 'movement' (dash is a kind of movement). I am not sure about the 'a fleet' bit.

Can you help me to learn more?

(Other definitions for dash that I've seen before include "Hurry; destroy (hopes)" , "Stroke < > to frustrate" , "Striking" , "scotch" , "Elan; punctuation mark" .)
