Raphy Leavitt RIIP: Leave itt att Thatt

The Deaths in 2015 site lists under August 5:

Raphy Leavitt, 66, Puerto Rican composer and orchestra leader

Note from Leavitt's wiki page:

Raphy Leavitt (September 17, 1948 – August 5, 2015) 

From the wiki pages of two notable persons mentioned on Leavitt's wiki page:

• Rafael Hernández (October 24, 1892 – December 11, 1965)
• Alberto Ferré Aguayo (February 17, 1904 – October 21, 2003)

So we now have an "October 21, __, __, 24/ Date Sequence" pattern-cluster.  To bridge the gap, we begin with October 22 wiki page.  Since the list are long, I limited my search as per usual by investigating only the years that end with 3 identical numbers.  I settled with the following event:

• 1777 – American Revolutionary War: American defenders of Fort Mercer on the Delaware River repulse repeated Hessian attacks in the Battle of Red Bank.

Note from the Battle of Red Bank wiki page:

• During the engagement, two of the ships, the 64-gun Ship-of-the-Line Augusta and the sloop of war Merlin ran aground on a shoal 

The ship named "Augusta" is an addition to the recent "Lion/Leo/August/Cat..." pattern-cluster... and we are in the month of August, so I consider this a prompt.  Note from Augusta's wiki page:

• HMS Augusta was a 64-gun third rate ship... launched on 24 October 1763 

So what are the chances of the ships launch date being October 24?!
Note this next excerpt from the Battle of Red Bank wiki page:

Commanders and leaders

 Christopher Greene John Hazelwood

 Karl Emil Kurt von Donop †

Even though the surnames Greene and Hazelwood stand out due to the recent "Forest/Wood..." pattern-cluster, Von Donop's wiki page reveals more in the line of dates: 

Count Carl Emil Ulrich von Donop(January 1, 1732^[1]– October 25, 1777)

So now we have an "October 21, 22, __, 24(x2), 25/ Date Sequence" pattern-cluster.  Not only that, His date of death is also an additon to the "Targeting Family Birthdays" pattern-cluster, given that 3 of my life partners family members are born on this day during different years.
Other notable persons mentioned on the Battle of Red Bank wiki page:

• George Washington (February 22, 1732 [O.S.February 11, 1731]– December 14, 1799)
• Charles Cornwallis, 1st Marquess CornwallisKG (31 December 1738 – 5 October 1805)
• William Howe, 5th Viscount Howe, KB, PC (10 August 1729 – 12 July 1814)

I'll leave itt with you to figure out the pattern-clusters in the dates and the cryptic phrase/communication couched in the names.

The cryptic phrase in his sur name "Leave itt" is obvious enough, butt there's also the English/French combination : "Lea vitt"... with the etymology of Lea being "field" and and "vitt" a cryptic form of French "vite" meaning "fast/hurry".  So, I'll "leave itt" att thatt!!
