At the Battle of Abu Klea: the breach was small and soon closed itself, leaving the intruders trapped inside the square, whose inner ranks faced-about and quickly defeated the intruders. See Battle of Abu Klea#Battle for the real events at Abu Klea.
:See the end of the section Battle of Abu Klea#Battle about a wrong or mistaken report in The Times newspaper after the battle that a British square broke.
# The restricted rocky irregular ground in that gully made it difficult to form a solid square to resist attack; that square came under intense attack from Sudanese. The square was flooded with a rush of tribesmen and a brutal hand-to-hand fight resulted. The BlackWatch were driven back but rallied and eventually drove the Sudanese out, with the square being reformed.
After the Mahdist War, the poet Sir Henry Newbolt got his information very wrong and wrote a poem named Vitaï Lampada describing a disastrous collapse. Or he may have intended to write a fictional "worst case" scenario, with the message "even if the worst happens, keep on fighting back", but many readers thought wrongly that he was describing real events. Frank Richards, a soldier in the Royal Welch Fusiliers around 1901, stated in his memoir entitled 'Soldier Sahib': "If a Welshman went into a pub where a Highland soldier was, of the regiment whose square was once broken by the Mahdi's dervishes in the Sudan, he would sometimes ask for a 'pint of broken-square'. Then he would have his bellyful of scrapping for the rest of the night, because this was an insult the Highlanders could not forgive." Robert Graves, who also served in the Royal Welch, told a similar story. In Spain in the Napoleonic War, at the Battle of García Hernández, three French squares were broken in the same day resulting in a very one sided victory for the British and Germans. For more information about infantry squares breaking or not breaking, see Battle of García Hernández#Commentary. In the Napoleonic Wars, when cavalry broke an infantry square, it was usually because one of more of:
The infantry were of poor quality.
The infantry were tired or disorganized or discouraged
It was raining, with risk of rain wetting the men's gunpowder, as firearms were at the time.
