Sangret and Wolfe subsequently met on a regular—yet unreliable—basis in which he would meet her at approximately 7 p.m., then return to barracks to answer the 10 p.m. , before returning to the wigwam (which he referred to as "the shack") to spend the night with her. Early in their courtship, this first wigwam he had constructed was discovered, and Wolfe evicted from the structure; in response, Sangret constructed a second, larger device for he and Wolfe to meet in his off-duty hours, again constructed using the traditional skills of his Cree ancestors he had honed in his youth, and again located close to his base on Hankley Common (then an army training ground regularly used for military exercises). Each structure was devised from long poles, saplings and branches covered by sheets of birch bark and bracken. The tools used for constructing these shelters included a small, crooked knife that is unique to the Cree.
