Given the known Draco (and other) family interest in mining in Ireland, the amphibious strike force by John Norreys and Francis Drake could be seen as "business by other means", driving the Scots from Ulster, so that the English could get control of the valuable mining assets, especially the gold.
etc
.. after I just stumbled on what is said to be an excerpt from Drake’s prayer, 1577, written in Portsmouth as he began his circumnavigation of the globe.
“Disturb us, Lord, when we are too well pleased with ourselves,
When our dreams have come true because we have dreamed too little,
When we arrive safely because we sailed too close to the shore.”
“Disturb us, Lord, to dare more boldly,
to venture on wider seas, where storms will show your mastery,
where losing sight of land, we shall find the stars.”
Gosh, that's bold talk, and wildly ambitious.
He must have inspired and terrified his crew in equal measure.
Boldly going where no English man had gone before.
(sailing at full speed off the edge of the map, there be dragons, and all that).
