Starve them! New England 1775 = Londonderry 1689

In late March 1775 the London government introduced laws called The Restraining Acts to punish the emerging revolution in America, outlawing direct trade between the 13 Colonies, and stopping all fisheries in New England. Some claimed that famine was the plan.

On March 18, in the House of Lords, the Marquis of Rockingham gave a speech which compared the proposed laws to the Siege of Derry. Macpherson's work had been published earlier in 1775 and is online here. The section that Rockingham quoted (shown below) is on page 206.

On 15 May 1775, John Dunlap's Pennsylvania Packet newspaper reported the Marquis' remarks to their readership, around 1/3 of the population of Pennsylvania were Ulster emigrants:

The speech was further reported in a series of other Pennsylvania newspapers. The editors knew their readerships well, and the historical parallels were undeniable. 

Dunlap of course was Strabane-born and would be the printer of the Declaration of Independence on 4 July 1776. The Ulster-Scots' ancestral experiences were what gave them the reason for revolution.
