The Moravians broke up their mission at Shamokin and soon thereafter the Indians abandoned the town.

October 31, 1755, a number of inhabitants gathered at John Harris’ and signed a petition for a fort at Shamokin as a protection against the French and Indians. On the same day a like gathering at Conrad Weiser’s sent a similar petition to the provincial authorities. John Shikellamy, son of the great vicegerent[vicegerent], went to Philadelphia and personally solicited the Governor to build a fort, saying “that such Indians as continue true to you want a place to come to and live in security against your and their enemies, and to Shamokin, when you erect the fort, they will come and bring their wives and children. Brethren, hasten the work; our warriors will assist you in building the fort.”

At a conference held at Carlisle January 17, 1756, this necessity was again brought to the notice of the Governor, who replied that he would build a strong house at Shamokin.

The fear of delay was because the French had for some time realized the importance of the strategic situation of Shamokin and if they could gain a foothold there the places below would be easy prey.

The Governor was determined that the fort should be built and made his plans accordingly. He informed the Board of Commissioners April 15, 1756, that he had on March 29 commissioned Lieutenant Colonel William Clapham to recruit a battalion for the purpose. This was the third battalion and was known as the Augusta Regiment. Major James Burd was second in command and Asher Clayton was commissioned adjutant of the battalion.

The regiment rendezvoused at Harris’ Ferry, where Governor Morris attended the recruiting and training in person. On June 12 orders were received to march.

A stockade was built at Halifax, where supplies were stored and a garrison maintained. While at this camp Colonel Clapham had a conference with the Iroquois chief, Oghagradisha, assuring him they were on their way to Shamokin.

Sufficient bateaux were built by July 1, when the regiment marched from Halifax, and by a tedious march the 400 troops reached Shamokin without mishap July 6 and immediately began the construction of the fort, which was built from plans drawn by E. Meyer, engineer of the British Government. It was called Fort Augusta in honor of the daughter of King George II.

Colonel Clapham pushed the work of construction with dispatch and September 23, wrote to Governor Denny, “The fort is now almost finished, and a fine one it is.” The construction required less than seven weeks upon the main works, but much time was employed in better protecting the fortress and in adding necessary buildings.

Much difficulty was experienced in obtaining adequate supplies of provisions and ammunition, as the only means of transportation were pack horses over a mountainous Indian trail or by bateaux and the latter was impossible during the severe winters.
