The British Occupation

The Mackenzie Diaries Detail British Preparations

Frederick Mackenzie’s Diary is a valuable source for information on the British Occupation of Rhode Island (Aquidneck Island). He began writing his diary in 1748 and continued to make entries faithfully until 1791. Some volumes of his diary have been lost, but fortunately we have his records of the British Occupation. Captain Mackenzie of the Royal Welsh Fusiliers came to the island with some six-thousand troops under the command of Henry Clinton. They took the island without opposition. The diary records the day to day activities of the British and occasionally the Rebel sides for almost three years. He describes everything he sees candidly and in remarkable detail. Mackenzie offers his opinion on what is being done correctly and what he would change. He includes drawings and maps. Mackenzie’s diary is a crucial British view of the Occupation.

Mackenzie’s Diary, paired with maps and diagrams from the Clinton Collection of the Clement Library, give us an idea of the preparations the British made for an American attack in June of 1778.

Mackenzie diary, June 6, 1778: “A new Chain of Redoubts lately constructed for the defense of Newport, are now complete. The ground in all parts extremely advantageous; but I think some of the Redoubts are not well placed and that in general they are too confined. They are called, Green-end, Dudley’s, Bannister’s, Irishes, and Tomini….”

Mackenzie expresses concerns about the Green End Redoubt. It is “very small” and intended for 3 guns. He laments that a soldier in one of these redoubts could only “fire directly forward…” He muses that the engineer designed it to “show his fancy.” The Green End Redoubt was on the high ground above Green End Pond to complete the outer walls of defense. Two thousand British and Hessian soldiers as well as Loyalist volunteers would be stationed along the redoubt lines. While construction was going on General Pigot ordered all trees to be chopped down and all houses burned down so that the enemy could be detected.* Later in the diary entry Mackenzie suggests that another redoubt should be built to the right of this redoubt to have better control over Easton’s Pond.

Mackenzie goes on to write: “Bannister’s and Irishes have a very good command of the adjacent ground.” He would have changed the position of Irishes Redoubt. The John Bannister family (Loyalists) had been at their Middletown country home. The British tore down the home next door that had belonged to George Irish who had left to join the Rebels. Marian Desrosiers in her book about the Banister family wrote:

“The redoubts the British built on both the Irish and Banister properties were about thirty to fifty yards on two sides and twenty yards in front of each redoubt to prevent American solders from storming the area.” (1).

Thomas Banister had left Rhode Island to fight with loyalists and the British took over his estate, “West Farm”, that included the high ground at Miantonomi Hill. Mackenzie wrote: “Little Tomini should certainly have been formed as an outwork to the great hill. A single gun, en barrette, in a small work, open behind, would have been of service, as it would command a good deal of ground unseen from Great Tomini.” He saw Little Tomini as a liability.
