Given the task definition, example input & output, solve the new input case.
This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.
Example: Passage: The outbreak of the Seven Years' War in Europe in 1756 resulted in renewed conflict between French and British forces in India. The Third Carnatic War spread beyond southern India and into Bengal where British forces captured the French settlement of Chandernagore in 1757. However, the war was decided in the south, where the British successfully defended Madras, and Sir Eyre Coote decisively defeated the French, commanded by Comte de Lally at the Battle of Wandiwash in 1760. After Wandiwash, the French capital of Pondicherry fell to the British in 1761. The war concluded with the signing of the Treaty of Paris in 1763, which returned Chandernagore and Pondichery to France, and allowed the French to have "factories" in India but forbade French traders from administering them. The French agreed to support British client governments, thus ending French ambitions of an Indian empire and making the British the dominant foreign power in India.
Question: Which french settlement did the British capture first, Chandernagore or Pondicherry?
Output: span
The answer "Chandernagore" is a word from the passage. So, the answer type is "span".

New input case for you: Passage: With Upper Burma securely under his control, Nyaungyan's successor Anaukpetlun marched south. His 14,000-strong land and naval forces sacked Prome on 13 July 1608 after a bloody siege of eight months. His 12,000-strong forces then attacked Toungoo, then ruled by his cousin, Natshinnaung, in August 1610. After a siege of 23 days, Natshinnaung agreed to become a vassal on 4 September 1610. But Natshinnaung was deeply unhappy with his reduced status, and secretly invited de Brito of Syriam to attack Toungoo. In July 1612, Syriam and Martaban forces ransacked the city for ten days, and left, taking Natshinnaung to Syriam. In response, Anaukpetlun's army of 13,000 left Ava for Syriam on 26 December 1612. A flotilla of 80 war boats and 30 cargo boats was also sent down the Irrawaddy to blockade the port. The Burmese forces overcame Portuguese outer defences, and finally blockaded the port on 24 February 1613. But Portuguese gunners and musketeers kept the Burmese at bay for 34 days while waiting for reinforcements from Goa to arrive. On 29 March 1613, however, the Burmese successfully brought down a section of the walls, from their tunnels below. The city was sacked. On 7 April 1613, de Brito his son and Natshinnaung were all executed by impalement. A month later, on 14 May 1613, Binnya Dala of Martaban, submitted. The ruler was nominally tributary to Siam but had ruled the region like a sovereign since the death of Naresuan in 1605. Alarmed, the Siamese sent an army to Ye, south of Martaban, to prevent the Burmese from marching down the coast. But the Siamese did not try to retake Martaban.
Question: When did the seige of Prome begin?
Output:
date
