The establishment of Halifax marked the beginning of Father Le Loutre's War.
 The war began when Edward Cornwallis arrived to establish Halifax with thirteen transports and a sloop-of-war on June 21, 1749.
 By unilaterally establishing Halifax the British were violating earlier treaties with the Mi'kmaq (1726), which were signed after Father Rale's War.
Cornwallis brought along 1,176 settlers and their families.
In 1750, the sailing ship Alderney arrived with 151 immigrants.
Municipal officials at Halifax decided that these new arrivals should be settled on the eastern side of Halifax Harbour.

During Father Le Loutre's War, the Mi'kmaq and Acadians raided in the capital region (Halifax and Dartmouth) twelve times.
On September 30, 1749, about forty Mi'kmaq attacked six men who were in Dartmouth cutting trees.
 Four of them were killed on the spot, one was taken prisoner and one escaped.
Two of the men were scalped and the heads of the others were cut off.
The attack was on the sawmill which was under the command of Major Gilman.
Six of his men had been sent to cut wood.
Four were killed and one was carried off.
The other escaped and gave the alarm.
 A detachment of rangers was sent after the raiding party and cut off the heads of two Mi'kmaq and scalped one.
This raid was the first of eight against Dartmouth.

The result of the raid, on October 2, 1749, Cornwallis offered a bounty on the head of every Mi'kmaq.
He set the amount at the same rate that the Mi'kmaq received from the French for British scalps.
 As well, to carry out this task, two companies of rangers raised, one led by Captain Francis Bartelo and the other by Captain William Clapham.
These two companies served alongside that of John Gorham's company.
The three companies scoured the land around Halifax looking for Mi'kmaq.

In July 1750, the Mi'kmaq killed and scalped seven men who were at work in Dartmouth.
Four raids were against Halifax Peninsula.
The first of these was in July 1750: in the woods on peninsular Halifax, the Mi'kmaq scalped Cornwallis' gardener, his son, and four others.
They buried the son, left the gardener's body exposed, and carried off the other four bodies.

In August 1750, 353 people arrived on Alderney and began the town of Dartmouth.
The town was laid out in the autumn of that year.

The following month, on September 30, 1750, Dartmouth was attacked again by the Mi'kmaq and five more residents were killed.

In October 1750 a group of about eight men went out "to take their diversion; and as they were fowling, they were attacked by the Indians, who took the whole prisoners; scalped ... [one] with a large knife, which they wear for that purpose, and threw him into the sea ..." The next year, on March 26, 1751, the Mi'kmaq attacked again, killing fifteen settlers and wounding seven, three of which would later die of their wounds.
They took six captives, and the regulars who pursued the Mi'kmaq fell into an ambush in which they lost a sergeant killed.
Two days later, on March 28, 1751, Mi'kmaq abducted another three settlers.
