Context paragraphs:
Brandywine order of battle: At the Battle of Brandywine on September 11, 1777 a colonial American army led by General George Washington fought a British-Hessian army commanded by General William Howe, 5th Viscount Howe.  Washington drew up his troops in a defensive position behind Brandywine Creek.  Howe sent Lieutenant General Wilhelm von Knyphausen's 5,000 troops to demonstrate against the American front at Chadd's Ford.  Meanwhile, Lieutenant General Charles Cornwallis took 10,000 troops on a wide flank march that crossed the creek and got in the rear of the American right wing under Major General John Sullivan.  The Americans changed front but Howe's attack broke through.

Battle of Wittstock: The Battle of Wittstock took place during the Thirty Years' War (1618-1648).  It was fought on 24 September (Julian calendar) or 4 October (Gregorian calendar) 1636.  A Swedish-allied army under general commanded jointly by Johan Banér and Alexander Leslie, later 1st Earl of Leven decisively defeated a combined Imperial-Saxon army, led by Count Melchior von Hatzfeld and the Saxon Elector John George I.  Leslie and Banér commanded two distinct armies: Banér commanded the Swedish main army (huvudarmén), and Leslie commanded the Army of the Weser.  Their subordinate officers included the Swedish Count and major General Lennart Torstenson, Lieutenant General James King (later first Lord Eythin), and Major General John Ruthven who is usually erroneously conflated with his uncle Patrick Ruthven who was also a Lieutenant General in the Swedish army, but not present at Wittstock.

Lieutenant general (United States): In the United States Army, United States Marine Corps, and the United States Air Force, lieutenant general (abbreviated LTG in the Army, Lt Gen in the Air Force, and LtGen in the Marine Corps) is a three-star general officer rank, with the pay grade of O-9.  Lieutenant general ranks above major general and below general.  Lieutenant general is equivalent to the rank of vice admiral in the other uniformed services.

Major general: Major general (short MG or Maj. Gen.) is a military rank used in many countries.  It is derived from the older rank of sergeant major general.  The disappearance of the "sergeant" in the title explains the apparently confusing phenomenon whereby a lieutenant general outranks a major general (although a major outranks a lieutenant, a lieutenant outranks a sergeant-major.)

Major general (United States): In the United States Army, United States Marine Corps, and United States Air Force, major general is a two-star general-officer rank, with the pay grade of O-8.  Major general ranks above brigadier general and below lieutenant general.  A major general typically commands division-sized units of 10,000 to 15,000 soldiers.  Major general is equivalent to the two-star rank of rear admiral in the United States Navy and United States Coast Guard and is the highest permanent rank during peacetime in the uniformed services.  (The higher ranks are temporary ranks linked to specific positions, although virtually all officers who have been promoted to those ranks are approved to retire at their highest earned rank.)
