MARCHING TO TICONDEROGA. Writing as commander of the Hudson Highlands, on February 22, Heath orders Wigglesworth to march his newly recruited 13th Massachusetts regiment to Ticonderoga: "In Consequence of Express orders from His Excellency General Washington you are immediately to march the Regiment Under your Command to Tyconderoga, to which place the Fifteen Battalions which are to be raised by this State, and all the Brigadier Generals in Continental Service residing in it are Destin'd." Wigglesworth is ordered to march even if the regiment is not fully recruited. On March 27, these orders are countermanded and Wigglesworth is now informed he should march his men to Peekskill: "Strict Order & Discipline are to be observed on the March." -- HEATH. Three retained drafts of autograph letters signed ("W Heath") to GENERAL JOHN BURGOYNE and General William Phillips, Boston, 18 January, 23 March and 3 June 1778. Together 5 pages, 4to, one laid down on separate leaf. DIRECTING THE SARATOGA CONVENTION ARMY. On January 18, Heath directs prisoner of war Burgoyne that all correspondance that he wishes to send to British commanders must first be inspected: "send down under cover all such letters and papers...I choose rather to see them myself than refer the Inspection of them to any other officer." On March 23, one month before Burgoyne was paroled, Heath informs him that he will not be allowed to send one of his officers with a message to Guy Carleton in Canada: "I will with great pleasure forward it to the Commanding officer at Albany and Desire him as soon as possible to convey it by a Flag to the first Post in the Possession of the British Troops in Canada." Heath also informs Burgoyne that he will see to the safe transport of supply to the Convention Army. On June 3, Heath writes to General Phillips, senior officer of the Convention Army after Burgoyne's departure, informing him that he should begin moving the 9th Regiment to Rutland. He orders that they draw four days provisions and "to take the same Rout and march the same distance each Day." Heath would eventually have Phillips arrested for insubordination. Together five items.
