The weak Ferozepore Brigade immediately went into hastily-dug support lines behind the Meerut Division's attacks on Aubers Ridge (9 May) and Festubert (15/16 May), where it was shelled but was not involved in the disastrous attacks. The 1/4th Londons also suffered a large number of casualties from sickness in its shallow trenches. After this, the reinforcement problems meant that the Indian Corps was not used offensively for the rest of the year, and 1/4th Londons spent the summer of 1915 taking turns in holding sections of trench in the La Bassée Road area and providing working parties while suffering a trickle of casualties.
