The Battle of Flers–Courcelette, which ran through September 22, commenced. The battle is notable for the commitment of Canadian and New Zealand troops to the Battle of the Somme, of which this is part, and for the first British use of tanks in World War One, and hence, the first use of tanks.The Commonwealth forces did advance, but there was less achieved than had been hoped for. Critics have focused somewhat on the ineffective use of tanks, both then and now, but then they were a new weapon. Some, such as Winston Churchill, who was significant in the development of the tank, felt that had tanks been used en mass, a breakthrough might have occured.
