The Senators are generally acknowledged as the greatest team in the early history of hockey, but Ottawa was far and away the smallest market in the league. In its early days, the city could offer good government jobs to players and keep expenses low. However, the NHL expansions in the 1920s hurt the Senators as fans were unwilling to come out to see visiting teams from the United States and revenues suffered. This, along with the Great Depression eventually took its toll on the team's finances. Even sitting out the 1931-32 season didn't relieve the pressure, and the team barely survived the 1933-34 season. The league's other owners, many also in difficulties, turned a deaf ear to the Senator's requests for financial assistance.
However, the league was not willing to lose another team so soon after the Philadelphia Quakers suspended operations (unlike Ottawa, they would never return). On May 14, 1934, the Senators were transferred to St. Louis, where they would be renamed the Eagles, named after the logo of Anheuser-Busch.
At the time, St. Louis was the 7th largest city in the United States, and was far larger than Ottawa. A St. Louis group had originally applied for an NHL franchise in 1932, but was turned down due to concerns about travel costs in the midst of the Great Depression. Teams travelled by train at the time.
It soon became apparent why the league was skittish about placing a team in St. Louis. While playing to large crowds in the St. Louis Arena, The team soon buckled under the strain of long train rides to Boston, Montreal and Toronto. The Eagles had to play a large number of games in Montreal and Toronto because they had assumed the Senators' place in the Canadian Division, which resulted in the longest road trips in the NHL, and diluted a natural rivalry with the Chicago Blackhawks. Under the circumstances, the results were predictable--a record of 11-31-6, dead last in the league. Eddie Gerard began the season as coach, only to be replaced by George Boucher.
Escalating travel costs chewed through what money the team had on hand, and the club sold players Syd Howe and Ralph Bowman to meet expenses. After the season, the club asked to suspend operations for the coming season and this was declined by the league. On October 15, 1935, the NHL bought back the franchise and players contracts for $40,000 and suspended its operations again. Under the agreement, the NHL paid for the players, and took back possession of the franchise. If the franchise was resold, the proceeds would go to the Ottawa Hockey Association. 
During the January 15, 1935 game at the Boston Garden versus the St. Louis Eagles, an ice making problem causes a patch with no ice at the east end. A rubber mat is placed over the patch and the teams switch ends every 10 minutes. The Bruins win 5-3.
