The engagement lasted two and a half hours without cessation, and over three hundred rebel dead were counted in or near the works, amongst them was Crispulo Aguinaldo, a brother of General Emilio Aguinaldo. The Spaniards lost 9 killed and 108 wounded.
After a short rest the division resumed the advance upon Imus, and bivouacked after marching about a couple of miles.
On the 25th the advance was continued on a broad front. Scarcely had the division marched for half-an-hour when the leading ranks came in sight of another line of entrenchments more than two miles long, six feet high, and five feet thick, well protected with cane fences in front, one of these being at a distance of 100 yards from the parapet.
Lachambre orders the centre to make a direct attack and the wings a flanking movement. The rebels retain their fire till the Spaniards arrive within two hundred yards, and then the parapet is crowned with flame both from small arms and lantacas. The scene of the day before was repeated, the parapet stormed, with a rebel loss of over six hundred. After a short halt the advance against Imus was resumed. The distance was short, and the appearance of the thousands of bayonets and the explosion of a few shells produced an indescribable panic amongst the inhabitants and the many who had come from other towns to assist in the defence.
They took to flight, disregarding the protests of their leaders Emilio Aguinaldo and Andrés Bonifacio. In order to cover his retreat, the former ordered the magazine to be blown up and the town to be burned. This delayed the advance of the Spaniards in the centre, but the wings moved forward and the thousands of fugitives were exposed to a flanking fire, and more than eight hundred of them bit the dust. It was afternoon before Lachambre could enter what remained of Imus, when as a mark of honour for their splendid services, the colour of the 74th Regiment of Native Infantry was raised upon the tower of the church—all the troops presenting arms and afterwards giving enthusiastic cheers.
Thus was taken the citadel of the Katipunan with a loss to the Spaniards of 25 killed and 129 wounded.
The taking of Imus gave General Polavieja an opportunity of offering an amnesty to the rebels, which he did not neglect. On the 26th of March he issued a proclamation offering pardon to all who had borne arms against the Royal Authority, or who had assisted the rebels, provided they presented themselves before Palm Sunday the 11th of April. Leaders of the rebels were to present themselves with their forces and arms.
On the 26th March the division, leaving a garrison in Imus, started for Bacoor to take the defences in reverse, and such was the effect on the rebels of their defeat at Imus and of the advance in overwhelming force, that they fled, and the division occupied Bacoor almost without firing a shot.
It was otherwise with Binacayan, for Marina’s Brigade having made a reconnaissance in force on the 28th, were received with a heavy fire, and after an hour’s skirmish in which some were killed on each side, they returned to their camp at Bacoor; Lachambre considering that an attack in that direction would result in a useless waste of life, for the advance would be along narrow causeways across swamps. Having received provisions and ammunition by sea from Manila, he returned with his division to Imus, the garrison of which had not been molested by the rebels.
At daylight on the 31st March, the division left Imus and marched across country in a westerly and southerly direction, fording numerous streams running at the bottom of deep ravines, as well as many irrigating canals and ditches. Soon after the start the right flank was fired upon, the fire increasing as the column moved forward. The engineers had to improve the approaches to the fords of the Rivers Julian and Batong Dalig under fire.
