All the time that Merritt was occupied in this important duty, the
enemy gave great annoyance to the working party by sweeping the
bridge with a section of artillery and a fire from the supporting
troops, so a small force was thrown across to drive them away.
When Merritt had passed two regiments over, they attacked, but
were repulsed. The work on the, bridge continued, however,
