The left column, with the Commander of the Forces, united with that under Major-General Gower in the suburbs of Buenos Ayres on the afternoon of July 3, and the whole army was placed in position. Two companies of the 1st Battalion, under Major Norcott, were immediately detached to occupy an advanced post, and became warmly engaged until dark; by which time they had completely dislodged a very superior force of the enemy from every point in their front which they were ordered to occupy. On the morning of the 4th this picquet was furiously attacked by several hundreds of the enemy, whose continued exertions to dislodge it proved fruitless. Major M’Leod joined the post about the middle of the day, and distinguished himself by his gallantry and judicious arrangements. This affair lasted until dusk, and our loss amounted to 2 officers (Lieutenants James Coane and Charles Noble) severely wounded, 1 sergeant and 1 rank and file killed, and 2 sergeants and 2 rank and file wounded. The two companies were relieved at night by a detachment of the 36th, and joined the army in its position. Orders were received during the early part of the night for the attack of the town at daylight on the 5th. The five companies of the 1st Battalion formed a part of the column of attack under Brigadier-General Craufurd and Lieutenant-Colonel Packe, leaving one company as an advanced guard to each division, supported by a light company. Major Travers commanded the advance of the right column and Major Norcott that of the left. The companies of the 2nd Battalion seem to have been attached to Sir Samuel Auchmuty’s division, the light battalion of which was divided into wings, each followed by a party of the 95th. These troops were all unloaded, and were directed not to fire until the columns had reached their final points and formed.
