the war on garrison duty at Montreal, retiring on half-pay in 1763. General James Murray wrote approvingly of Hazen in 1761, "He discovered so much still bravery and good conduct as would justly entitle him to every military reward he could ask or demand". Land development During the siege of Quebec, Hazen had met Gabriel Christie, then a deputy quartermaster. Christie owned some land in the Richelieu River valley south of Montreal, and wanted to expand his holdings. (Christie later became one of the largest landowners in Quebec.) After the war, Christie and Hazen jointly purchased the seigneuries of Sabrevois and Bleury, located on the east bank of the Richelieu near Fort Saint-Jean. They also leased land on the west side of river from the Baron of Longueuil. These holdings gave them almost exclusive control over the land holdings around Saint-Jean, which is the northernmost navigable point reachable from Lake Champlain. Christie, who was still in military service, was frequently away from the land, so Hazen developed the land while Christie provided the funding. Hazen constructed a manor house at Iberville, and two mills, and set about selling timber and other business endeavours. In 1765, Hazen was also appointed a deputy land surveyor, and a justice of the peace. As part of his business dealings, he offered General Thomas Gage, then in command of British forces in New York City, facilities and lumber for military use. Gage was uninterested at the time, letting Hazen know that he would keep the offer in mind, if the need for military movements became necessary in the area. Hazen expanded the business of the seigneuries, but his aggressive development also incurred debts, which caused friction with Christie. In 1770, Christie, unhappy with the debts, eventually demanded an accounting. This ultimately led to a division of the holdings, with Hazen receiving the southern portion of the Bleury seigneurage, styled Bleury-Sud. Hazen and Christie were in and out of court for years afterward over control of these lands; Christie eventually won complete control over those lands after the American Revolution. In 1762 Hazen's brother John settled Haverhill, New Hampshire, in the far north of that province on the east side of the Connecticut River, and in 1764 Jacob Bayley settled Newbury, in what is now Vermont, across the river from Haverhill. Hazen had shares in both of these settlements; he also acquired land west of the
