After arriving in Egypt, it joined the 10th Indian Division when it was formed on 24 December. It served on the Suez Canal Defences, notably taking part in the Actions on the Suez Canal on 3–4 February 1915. In July 1915, the brigade was detached to Aden with &lt;a href="1/B%20Battery%2C%20Honourable%20Artillery%20Company"&gt;1/B Battery, HAC&lt;/a&gt; and &lt;a href="1/1st%20Berkshire%20Royal%20Horse%20Artillery"&gt;1/1st Berkshire Battery, RHA&lt;/a&gt;. They fought a sharp action at Sheikh Othman on 20 July that removed the Turkish threat to Aden for the rest of the war, before returning to Egypt in September. In November 1915, the brigade left the division and moved to Mesopotamia.
