let me try normal word order.

on a lone island lived a lovely maiden coming of age and thinking of men she loved but never touched;far away she saw some fishermen.

day and night she prayed for men's coming, but no knight was seen, no steps heard.wind caressed her heaving breasts yet her lonely heart was never caressed.

one night, horses were galloping like thunder.the loudness woke her up in a stir terrified.she then hid behind a rock. she was about to see what mystified her

one handsome man,waving a huge flag 'shen the duke, in white on a white horse;the other, a strong man in black on a chariot deeply carved with large 'monkey the spook'

with no word, the spook struck with his sword
the duke and then fended it off with his long spear.
now waves broke on rocks like drums,fish jumped to see and frogs sang to cheer.

after 300 rounds no winner was declared.suddenly a rabbit run with full speed.the lass came out from her hiding place with joy. she asked the men to recede.

the stunned men stared at the sweet girl,her face red and her heart beating fast.the men then handed over their weapons.her dream men now had come at last.

what do these words mean?
heaving breasts
a stir terrified,
a huge flag 'shen the duke
'monkey the spook
now waves broke on rocks like drums
