1st Dec 1941 Sir Robert Brooke-Popham has ordered “2nd Degree of Readiness”. Troops were ordered back to barracks and Volunteers were mobilized.
5th Dec 1941 War Office gave authority to Brooke-Popham to execute Operation Matador, upon the following situations:
a) If he had information that Japanese expeditions were advancing with apparent intention on the Kra Isthmus; OR
b) If the Japanese violated any other part of Thailand.
6th Dec 1941, a Hudson from No.1 RAAF Squadron based in Kota Bahru reported enemy ships convoys 265 mile north. However, after consultation with the Navy, Brooke-Popham hesitated and instead ordered “No. 1 Degree of Readiness” – ready for immediate operations and prepare for enemy attack without prior warning. No order for Operation Matador was executed.
In Kuala Lumpur, during a conference between GOC Malaya Command & GOC III Indian Corps, Percival acted on the sighting reports by No. 1 RAAF. He advised Heath to make preparatory launch of Matador and ordered “Raffles” – Code word for “Action Alert”
